Our Verdict
This 2017 Mercedes-Benz C-Class shows a well-preserved mileage profile and recent clean test passes, though prospective buyers should note the administrative retests in its history. Overall, it presents a solid opportunity for anyone seeking a high-performance grey petrol saloon.
When viewing this 2017 Mercedes-Benz C-Class, investigate the circumstances behind the consecutive same-day fail-and-pass test results recorded in July 2024 and July 2025. Check whether these were due to administrative errors or minor rectifications that were resolved immediately. Ensure you inspect the physical service booklet and supporting invoices to corroborate the vehicle's maintenance schedule alongside the digital MOT history.
Negotiation should factor in the high-performance nature of the 3982.0cc engine, which commands higher consumable costs, particularly for tyres and braking components. Confirm the condition of high-wear items such as suspension arms and headlamps, which are noted as common failure points across the wider model range. A thorough pre-purchase inspection by a qualified specialist is strongly advised to verify mechanical integrity before finalising the purchase.
Running a high-performance 3982.0cc petrol Mercedes-Benz C-Class involves significant financial commitments. Fuel economy will be low during urban driving, and annual vehicle excise duty (road tax) will sit at the higher tier applicable to performance models of this era. Insurance groups for this engine variant are typically at the maximum end of the scale.
Maintenance and servicing costs will exceed standard family hatchback expenses, with premium tyres, specialist servicing, and potential replacement parts demanding a generous upkeep budget. Owners should anticipate regular expenditure on consumables. The estimated annual running cost is £3,200-£4,000.
Pay close attention to the common model failure areas identified in national data, specifically the suspension arms, tyres, and headlamps. Although no specific defects were recorded during the 2023, 2024, or 2025 tests, a physical check of the suspension bushings and dampeners is essential for a vehicle of this power output.
Inspect the tyres across all four corners for even tread wear and check the age of the rubber, as powerful rear-wheel-drive saloons can wear rear tyres quickly. Verify that all lighting equipment, including complex headlamp units, operates correctly and shows no signs of moisture ingress or cracking.
First registered in July 2017, this grey Mercedes-Benz features a substantial 3982.0cc petrol engine and has covered 41,743 miles by July 2025. Its MOT history reveals consecutive years of passing following initial test failures on the same day in both 2024 and 2025, though no specific component defects were logged during these failures. With a mileage well below the model average, it offers an intriguing prospect for performance saloon enthusiasts.
The Mercedes-Benz C-Class achieves an average MOT pass rate of 82.2% across the UK, with suspension arms, tyres, and headlamps noted as the top failure reasons.
