Our Verdict
Proceed with caution and a thorough inspection before buying this 2012 Mercedes-Benz C diesel. The high mileage and recurring corrosion-related advisories suggest it has been used heavily and may need ongoing maintenance.
Given the MOT history, prioritise a review of the service records to confirm regular oil changes and timing chain or belt intervals on the 2987cc diesel unit, as high mileage increases wear risk. Use the August 2023 failure (side repeater light, corroded brake pipe, coil springs, anti-roll bar dust covers) as a negotiation point — these are not catastrophic but reflect deferred minor maintenance you may inherit. Inspect the vehicle in person for evidence of the noted corrosion on the rear subframe and steel brake pipes, as the 2025 test still flagged both as corroded though not excessive.
As a 3.0-litre diesel registered in 2012, this C-Class will fall into a higher VED band than smaller petrol equivalents, though exact tax depends on current rates for pre-April 2017 diesels. Insurance group is likely mid-to-high for the era given the engine size and luxury branding. With 174,649 miles on the clock, budget for above-average maintenance such as suspension bushes, brake pipes and possibly subframe treatment; estimated annual running cost including fuel, tax, insurance and typical upkeep is £1,400-£1,800.
The MOT history shows a failed test on 2023-08-16 for an offside side repeater with reduced light intensity, so check all exterior lights function correctly and have not been poorly repaired. Corrosion is a recurring theme: 2024 and 2025 advisories note rear subframe corrosion, o/s front steel brake pipe corrosion, and corroded coil springs front and rear — physically inspect these areas underneath for scale or weakening. Anti-roll bar ball joint dust covers were severely deteriorated from 2023 to 2024, so examine the front suspension for torn gaiters and any play in the ball joints noted at 164,297 miles.
This blue 2012 Mercedes-Benz C 3.0-litre diesel (KP12CVE) has covered 174,649 miles as of its August 2025 MOT, well above typical use for a 13-year-old car. MOT history shows a single failure in August 2023 for a side repeater light and several wear items, with repeated advisories for corrosion on brake pipes, coil springs, subframe and anti-roll bar dust covers. The vehicle has passed its last three MOTs but the consistent pattern of corrosion notes indicates ageing components that will require attention.
No aggregate MOT reliability data is available for the Mercedes-Benz C, so assessment is limited to this vehicle's individual history.
