The Mercedes-AMG G 65 is one of the most unusual vehicles in the history of the G-Class. Underneath its almost military-style body sits a six-liter V12 engine with two turbochargers, while the traditional G-Class construction combines permanent all-wheel drive, low-range gearing, three differential locks, and a ladder-frame chassis.

This particular car was first registered on November 27, 2016. Its recorded mileage at the time of the dealer visit was 23,895 km.

According to the estimate from the official Mercedes-Benz dealer in Dubai, the complete service package, including front axle repairs, a window regulator, and new wiper blades, came to AED 28,362.18 including VAT.

The scheduled maintenance itself—Service B, spark plugs, coolant, transmission service, brake fluid, and axle oils—accounted for AED 12,307.70 before VAT. The remainder of the estimate relates to additional repairs.

Here is what makes the G 65 so special and how its Dubai service bill was calculated.

What Car Is This?

The dealer document identifies the vehicle as a Mercedes-AMG G 65. It is a classic W463-generation G-Class with the factory model designation 463.274.

The car belongs to the updated version of the G 65. Following the 2015 model update, output from the V12 increased to 463 kW, or 630 hp, while maximum torque remained at 1,000 Nm. The 0–100 km/h sprint took 5.3 seconds. Official Mercedes-Benz specifications

Those figures remain remarkable for a large ladder-frame SUV.

What Makes the Mercedes-AMG G 65 Unique?

A Six-Liter V12 in a G-Class

The car’s defining feature is its 5,980 cc AMG V12 biturbo engine.

The G 65 was the first production G-Class fitted with a six-liter V12. At launch, Mercedes-Benz described it as the world’s most powerful series-production off-roader. Its engine produced 1,000 Nm, while the electronically limited top speed was 230 km/h. Official Mercedes-AMG G 65 history

This is not merely a more powerful G 63. The G 65 has a completely different powertrain character: twelve cylinders, exceptionally smooth power delivery, and enormous torque throughout much of the operating range.

Twenty-Four Spark Plugs

The complexity of the V12 becomes obvious from the dealer estimate alone. The engine requires 24 spark plugs—two for every cylinder.

Even a spark plug replacement becomes a significant expense:

• replacement labor — AED 1,531.20;
• 24 spark plugs — AED 1,596;
• three units of specialist lubricant — AED 583.80;
• total — AED 3,711 before VAT.

A normal four-cylinder engine generally requires four spark plugs, while most V8 engines use eight. The G 65 needs twenty-four.

Ladder-Frame Chassis and a Genuine Off-Road Drivetrain

Despite its supercar-level engine, the G 65 retained the traditional G-Class construction:

• a separate ladder frame;
• permanent all-wheel drive;
• low-range gearing;
• three lockable differentials;
• the classic architecture of the original W463.

Mercedes-Benz officially emphasized that even after the increase to 630 hp, the G-Class retained its ladder-frame chassis, permanent all-wheel drive, low-range transfer gearing, and three differential locks. Mercedes-Benz on the updated G-Class

This combination is what makes the G 65 unique: it is effectively a traditional utility off-roader with a luxury interior and a six-liter AMG V12.

A Vehicle from a Different Era

Modern AMG vehicles use smaller engines, hybrid systems, and newer electronic architectures. The G 65 comes from a very different era: a huge V12, seven-speed automatic transmission, ladder-frame construction, and mechanical differential locks.

That makes the car interesting for more than its power. It represents a rare engineering combination that would be extremely difficult to recreate today.

Where Was the Car Serviced?

The estimate was prepared by Gargash Enterprises L.L.C., the authorized general distributor of Mercedes-Benz vehicles in Dubai, Sharjah, and the Northern Emirates.

The work was quoted by the Sheikh Zayed II Branch.

The main details were:

• vehicle check-in date — June 16, 2026;
• estimate issue date — July 6, 2026;
• mileage — 23,895 km;
• service advisor — Ammar Shah;
• dealer labor rate — AED 528 per hour;
• estimate validity — 30 days.

Total Cost of the Service and Repairs

The dealer estimate was structured as follows:

• parts — AED 12,937.40;
• labor — AED 13,182.20;
• consumables — AED 892;
• total before VAT — AED 27,011.60;
• 5% VAT — AED 1,350.58;
• final total — AED 28,362.18.

It is important to separate scheduled maintenance from repair work.

Scheduled service and fluid replacement accounted for AED 12,307.70 before VAT. The additional front axle work, wiper replacement, and window regulator repair added another AED 14,703.90 before VAT.

Service B: AED 4,107.50

The foundation of the maintenance visit was the scheduled Service B package for a vehicle more than 49 months old.

It included:

• quick computer test — AED 158.40;
• Service B procedure — AED 1,848;
• cleaning and inspection of both engine air filters — AED 211.20;
• cabin dust filter replacement — AED 105.60;
• cleaning and lubrication of the mechanical sunroof components — AED 52.80;
• chassis inspection — AED 105.60;
• vehicle wash — AED 20;
• brake cleaner and small consumable materials — AED 65;
• cleaning the evaporator and air-conditioning system — AED 105.60;
• 24-hour roadside assistance package — AED 50;
• windscreen cleaning fluid — AED 15.40;
• fuel additive — AED 126.70;
• first filter parts kit — AED 352.10;
• second filter parts kit — AED 103.60;
• separate filter — AED 235.20;
• sealing ring — AED 8.40;
• 10.5 liters of engine oil — AED 543.90.

The complete Service B package came to AED 4,107.50 before VAT.

The 10.5-liter engine oil capacity is appropriate for an engine of this scale. However, the engine oil itself represents a relatively small part of the total. Most of the Service B cost comes from dealer labor, inspections, and additional service procedures.

Why Service B Is Especially Important in Dubai

In Dubai, standard maintenance intervals must be considered alongside heat and dust exposure.

Engine Air Filters

Dust and fine sand can contaminate the engine air filters more quickly. The estimate includes cleaning and inspection of both elements, with replacement if necessary.

Unrestricted airflow is particularly important for a twin-turbocharged V12. Dirty filters increase intake resistance and may affect engine operation under load.

Cabin Filter and Evaporator

The estimate includes both cabin dust filter replacement and air-conditioning evaporator cleaning.

In Dubai, the air-conditioning system operates for most of the year. A contaminated filter restricts airflow, while dust and moisture on the evaporator can cause unpleasant odors and reduce cooling performance.

Sunroof

Cleaning and lubrication of the mechanical sunroof components are listed separately.

Dust and sand can enter the guide rails, mix with old lubricant, and form an abrasive paste. Periodic cleaning therefore makes sense in Dubai even when the sunroof is rarely used.

Replacing 24 Spark Plugs: AED 3,711

The dealer schedule specifies spark plug replacement every 60,000 km or three years.

The cost was:

• 2.9 hours of labor — AED 1,531.20;
• 24 spark plugs at AED 95 each — AED 1,596;
• specialist lubricant — AED 583.80;
• total — AED 3,711 before VAT.

This is one of the defining costs of owning a G 65. Even a basic maintenance operation costs considerably more than on most other G-Class models because the V12 uses 24 spark plugs.

For a low-mileage car, owners must consider age as well as distance. This is why the estimate specifies an interval of 60,000 km or three years.

Coolant Replacement: AED 1,039

The dealer schedule specifies coolant replacement every 150,000 km or five years.

The estimate included:

• coolant replacement and system leak inspection — AED 528;
• ten units of original coolant — AED 511;
• total — AED 1,039 before VAT.

For a G 65 in Dubai, this is one of the most important procedures. A six-liter twin-turbocharged V12 generates substantial heat, while the cooling system must operate in very high ambient temperatures during summer.

The following items should also be inspected:

• cleanliness of the main and auxiliary radiators;
• operation of the electric cooling fans;
• condition of the coolant hoses;
• expansion tank sealing;
• system performance under load with the air conditioning operating;
• sand and debris trapped between the heat exchangers.

Fresh coolant cannot perform properly if the radiators are externally blocked by dust.

Automatic Transmission Service: AED 1,841.70

The vehicle uses an AMG SPEEDSHIFT PLUS 7G-TRONIC seven-speed automatic transmission.

According to the estimate, the service interval is every 60,000 km or four years.

The quoted work included:

• main transmission oil and filter replacement labor — AED 633.60;
• additional procedure for the 722.9 transmission with start-stop functionality — AED 105.60;
• ten units of transmission fluid — AED 707;
• six screws — AED 79.80;
• molded elastomer seal — AED 95.90;
• overflow pipe — AED 14.70;
• transmission oil filter — AED 197.40;
• sealing ring — AED 7.70.

The complete transmission service cost AED 1,841.70 before VAT.

Age-based transmission servicing is especially important in Dubai. During slow-moving traffic, the transmission receives less natural airflow, while ambient temperatures remain high even after sunset.

After the service, the transmission should be checked for seepage, correct fluid level at the specified temperature, and proper operation in every driving mode.

Brake Fluid: AED 794.60 Across Two Estimate Entries

The document contains two identical brake fluid replacement packages:

• replacement with Service B — AED 397.30;
• replacement with Service A — AED 397.30.

Each entry includes:

• 0.6 hours of labor — AED 316.80;
• brake fluid — AED 80.50.

Both entries are included in the total, resulting in AED 794.60 before VAT.

Before approving the repair order, it would be sensible to ask the service advisor whether two separate operations are intended. During a single workshop visit, the brake fluid would normally only be replaced once.

The document specifies an annual replacement interval. In Dubai, brake fluid condition deserves attention because of high temperatures, coastal humidity, and the considerable weight of the vehicle.

Front and Rear Axle Oil: AED 813.90

The dealer schedule specifies changing the front and rear axle oil every 45,000 km or three years.

The estimate included:

• front axle oil replacement — AED 105.60;
• rear axle oil replacement — AED 105.60;
• transmission oil — AED 482.30;
• four screw plugs — AED 64.40;
• filling plug — AED 23.80;
• two sealing plugs — AED 32.20.

The complete cost was AED 813.90 before VAT.

The G 65 has a complex off-road drivetrain, so servicing does not end with the automatic transmission. Both axles, the transfer case, and the differential-locking system also require attention.

If the vehicle is driven in the desert, the drivetrain should be inspected for leaks and the underside cleaned after driving through sand.

Front Axle Repair: AED 9,347.70

The most expensive part of the estimate was the front joint work and replacement of both front axle boots.

Labor:

• removal and installation of the left front axle joint housing, including inspection — AED 2,323.20;
• equivalent work on the right side — AED 2,323.20;
• replacement of both front axle boots — AED 1,003.20.

Labor for this section totaled AED 5,649.60.

Additional parts and materials:

• long-life grease — AED 151.20;
• two tapered roller bearings of the first type — AED 313.60;
• two tapered roller bearings of the second type — AED 763;
• two sealing rings — AED 627.20;
• two seals — AED 37.80;
• another two seals — AED 417.20;
• two seal holders — AED 175;
• two tensioning straps of the first type — AED 30.80;
• two tensioning straps of the second type — AED 49;
• two axle boots — AED 723.80;
• two securing elements — AED 29.40;
• two additional sealing rings — AED 165.20;
• two protective rings — AED 187.60;
• three cotter pins — AED 27.30.

Parts and materials for this section totaled AED 3,698.10.

The complete front axle repair came to AED 9,347.70 before VAT.

Why Axle Boots Matter in Dubai

An axle boot keeps lubricant inside the joint while preventing sand and contamination from entering.

High temperatures accelerate the ageing of rubber. Once a boot develops a crack, grease can escape and dust or sand can enter the joint. Wear of the joint and its bearings then increases rapidly.

In Dubai, even minor seepage or a small crack in an axle boot should not be postponed until the next major service.

Wiper Blade Replacement: AED 363.20

The estimate included replacement of the front and rear wiper blades:

• labor to replace the two front blades — AED 52.80;
• labor to replace the rear blade — AED 52.80;
• rear wiper blade — AED 79.10;
• front wiper blade kit — AED 178.50.

The total was AED 363.20 before VAT.

In Dubai, wiper blades often deteriorate because of sunlight and heat rather than frequent use. The rubber edge hardens, begins leaving streaks, and can scratch a dirty windscreen.

During dusty conditions, the wipers should not be operated on dry glass. A sufficient amount of washer fluid should be used first.

Left Rear Window Regulator: AED 4,993

Another significant repair item was replacement of the left rear door window regulator:

• removal and installation labor — AED 1,953.60;
• new window regulator — AED 3,039.40;
• total — AED 4,993 before VAT.

The inner door trim must be removed to complete the repair.

High cabin temperatures can increase stress on plastic guides, cables, seals, and the mechanism’s lubricant. The glass should move smoothly without being restricted by hardened or dry seals.

Three Levels of Cost for This Visit

The estimate can be divided into three levels.

Service B Only

The basic dealer Service B package:

• AED 4,107.50 before VAT.

Complete Scheduled Maintenance

Service B, spark plugs, coolant, transmission service, brake fluid, and axle oils:

• AED 12,307.70 before VAT.

Complete Service and Repairs

Scheduled maintenance plus front axle repairs, wiper blades, and the rear window regulator:

• AED 27,011.60 before VAT;
• VAT — AED 1,350.58;
• final total — AED 28,362.18.

More than half of the cost of this visit therefore relates to additional repairs rather than scheduled maintenance.

What G 65 Owners Should Monitor in Dubai

V12 Cooling

The six-liter V12 biturbo creates a substantial thermal load. Owners should monitor not only the coolant but also radiator cleanliness, fan operation, hose condition, and engine temperatures in traffic.

Air Filters

After dust storms or driving through sand, the filters should be inspected before the normal scheduled interval. This applies to both the engine air filters and the cabin filter.

Air Conditioning

Evaporator cleaning is already included in Service B. Owners should also monitor vent temperatures, flap operation, and the air-conditioning drain system.

Axle Boots and Seals

The front axle boots already required replacement. The remaining rubber drivetrain and suspension components should be inspected during every service.

Battery

The battery is not included in the estimate, but its condition should be tested regularly in Dubai’s heat. This is particularly important if the vehicle is rarely driven or stored for extended periods.

Tires

With 630 hp, 1,000 Nm, and considerable vehicle weight, tire condition is critical. Owners should check not only tread depth but also the manufacturing date, cracking, pressure, and internal damage.

Brakes

The dealer specifies annual brake fluid replacement. The pads, discs, and flexible brake hoses also require careful inspection, especially when the vehicle is frequently driven in the city or at motorway speeds.

Sunroof and Window Regulators

Dust in the guide rails and dried lubricant increase the load on electric motors. These mechanisms should be periodically cleaned and lubricated before they begin to move unevenly or make unusual noises.

What Should Be Confirmed with the Dealer?

Before approving an estimate like this, I would clarify three points:

1. Why brake fluid replacement appears as two identical entries.
2. Which filters are included in Service B and whether both engine air filters will be replaced or only cleaned.
3. Which front joint components definitely require replacement after disassembly, since the labor description specifies inspection and replacement where necessary.

Two lines in the document also contain the word “FREE” in their descriptions—the vehicle wash and roadside assistance—while the amount column shows AED 20 and AED 50 respectively. Their purpose should also be confirmed with the service advisor.

Conclusion

The Mercedes-AMG G 65 is unique because it combines three very different worlds:

• the classic ladder-frame construction of the G-Class;
• a genuine off-road drivetrain with low-range gearing and three differential locks;
• a six-liter AMG V12 biturbo producing 630 hp and 1,000 Nm.

The trade-off is complex and expensive maintenance. The engine requires 24 spark plugs and 10.5 liters of oil, while the transmission and both axles have their own fluids. The front axle joints also contain numerous bearings, boots, seals, and retaining components.

The basic Service B package in this dealer estimate costs AED 4,107.50 before VAT. The complete scheduled maintenance package, including spark plugs and the main fluids, costs AED 12,307.70 before VAT.

Once the front axle repair, wiper blades, and window regulator are included, the official Mercedes-Benz dealer in Dubai estimated the entire visit at AED 28,362.18 including VAT.

That is the real cost of servicing and repairing a Mercedes-AMG G 65 V12 with 23,895 km at an official dealer in Dubai.
