Our Verdict
Proceed with caution due to high mileage, but the recent MOT history is clean. This 2018 Mercedes-Benz GT is a high-performance machine that requires careful scrutiny of its maintenance records.
Given the large 3982cc petrol engine, your primary focus should be on the service history. High-performance vehicles like this GT demand strict adherence to manufacturer service intervals to maintain mechanical integrity. Ask for proof of oil changes and component inspections, especially given the mileage has climbed from 35,849 in 2023 to over 84,000 in 2026.
Negotiate based on the mileage. This vehicle has covered significantly more ground than the typical example in our database. Ensure you check the condition of high-wear items such as brakes, suspension components, and tyres, as these are common areas of concern for performance cars with this level of usage.
Running this 4.0L petrol engine will be expensive. Expect high fuel consumption consistent with a large-capacity performance engine, and insurance groups for this model are typically high. Tax bands for a 3982cc vehicle will also be at the upper end of the scale.
Maintenance costs are likely to be substantial. Beyond standard servicing, the cost of replacement parts for a Mercedes-Benz GT can be significantly higher than for a standard saloon. Budget for premium tyres and high-performance braking systems, which will require more frequent and costly replacements.
Inspect the tyres thoroughly. While the recent MOT history shows no defects, the aggregate data for this model indicates that tyres are a top reason for MOT failures. Check for uneven wear which could indicate suspension issues.
Pay close attention to the mechanical components related to the high mileage. Since the car has covered nearly 50,000 miles in the last three years, check for any signs of fluid leaks or unusual noises from the engine bay and undercarriage. Although the MOTs have passed, they are snapshots in time and do not reflect the overall mechanical state of the vehicle.
This 2018 Mercedes-Benz GT, finished in black, has covered 84,288 miles as of its last MOT in April 2026. While the MOT history shows a recent failure in March 2026, it was followed by a clean pass shortly after. The vehicle has seen significantly higher usage than the model average of 2,844 miles per year, which is a key factor for any prospective buyer.
The Mercedes-Benz GT shows a high average MOT pass rate of 94.1% across 1,545 analysed vehicles, though tyres are a frequent failure point.
