Our Verdict
This 2021 Mercedes-Benz C-Class diesel is a solid choice with good mileage progression and clean recent MOT history, but the brake wear advisories suggest upcoming maintenance costs. The vehicle has covered 40,349 miles in four years, which is reasonable for a Mercedes-Benz C-Class, and the MOT advisories are minor and expected for its age. While there are no major concerns, you should budget for brake components and verify the full service history before purchase.
When inspecting this vehicle, pay close attention to the brake system given the recent advisories for worn pads and discs. Request the full service history to verify regular oil changes and fluid inspections, as diesel particulate filter maintenance is crucial for Mercedes-Benz diesels. Check for any signs of water ingress around door seals and the boot area, which are common issues in older C-Class models. Negotiate a reduction in price to account for the imminent brake service, which could cost £300-£500 for parts and labour. Verify that the Diesel Particulate Filter (DPF) has been regenerated recently and that the vehicle has been regularly driven on longer motorway journeys to keep the DPF clear.
The 2021 Mercedes-Benz C 1950 CDI is likely in insurance group 25-30, placing it in the medium-to-high insurance bracket for a executive car of this size. Road tax for a 2021 diesel C-Class falls in the £160-£200 annual range depending on exact engine variant. Fuel economy for this diesel engine should deliver around 55-60 MPG on motorway driving, making it economical for company car users despite higher tax rates. Annual maintenance costs for a Mercedes-Benz C-Class typically range from £1,200-£1,800 including servicing, with brake replacements needed approximately every 40,000 miles. Considering fuel, tax, insurance and maintenance, expect total annual running costs between £2,000-£2,500.
Given the recent MOT advisories, inspect the front and rear brake discs for scoring or grooves, and check brake pads for remaining thickness. The 2021 C-Class diesel is prone to electronic issues, so test all electrical systems including infotainment, climate control and window motors thoroughly. Check the Diesel Particulate Filter indicator and ensure no warning lights are present, as DPF issues can be expensive to resolve. Inspect the suspension for any knocks or uneven tyre wear, which may indicate worn bushings or components. Look for any signs of oil leaks under the vehicle, particularly around the engine bay and gearbox area.
This 2021 Mercedes-Benz C-Class diesel (1950cc) in grey has demonstrated sensible usage with 40,349 miles on the clock as of February 2026. The MOT history shows three consecutive passes with only advisory notices for brake pad and disc wear, indicating the vehicle has been well-maintained. The mileage progression from 19,106 miles in March 2024 to 40,349 miles in February 2026 averages around 10,000 miles per year, which is typical for a executive saloon. The lack of aggregate model data prevents broader reliability comparisons, but the individual vehicle history is positive.
No aggregate reliability data is available for the Mercedes-Benz C-Class model to provide broader context about typical failure rates or common issues across the range.

- Hybrid Battery / Charging BugsModerate
PHEV models can occasionally show charging faults or fail to engage electric mode due to software glitches.
- Frameless Door Glass Regulator & Microswitch StickingModerate
The frameless door windows must automatically index down 10mm when opening. Faulty door handle microswitches or regulator friction can cause the glass to catch against the roof weatherseal, causing seal tears and wind rush.
- M282 1.3L Turbo Electric Wastegate Actuator BindingSerious
On CLA 180 and CLA 200 petrol models, moisture and heat cycling can cause the electronic turbocharger wastegate actuator linkage to bind, triggering reduced engine power and an engine warning light.
