Our Verdict
Exercise caution with this vehicle. Whil
Prospective buyers should prioritise the issues raised in the August 2026 MOT. The mention of corroded brake pipes on both the nearside and offside front is a significant point for negotiation, as this often requires replacement rather than a simple fix. Additionally, the play in the front wheel bearings and the condition of the tyres indicate that the vehicle has not had preventative maintenance recently.
Request full service records to see if major high-mileage intervals have been met, specifically regarding the transmission and engine components. Given the 177,971-mile odometer reading, verify when the last major service was performed and check for any evidence of oil leaks, which are common in older diesel engines of this displacement.
The 2148cc diesel engine typically offers a balance of motorway efficiency and power, though fuel economy will be lower than a newer equivalent. Tax will fall into a standard bracket for 2009 diesel emissions, and insurance groups for the C-Class are generally moderate, though this varies by driver profile.
Maintenance costs are likely to be higher than average for a car of this age due to the high mileage. Between fuel, tax, insurance, and the anticipated need for brake and bearing repairs, the annual expenditure will be significant.
Focus your inspection on the front end of the vehicle. Specifically, check the front brake pipes for visible corrosion and grease, as noted in the August 2026 MOT. During a test drive, listen for a humming or droning noise from the front, which would confirm the 'slight play' reported in the wheel bearings.
Inspect all four tyres closely; the MOT record explicitly mentions tyres worn close to the legal limit on the front and a perishing/cracking rear nearside tyre. Finally, check the steering and suspension for any knocks, referencing the 2025 failure of the anti-roll bar linkages and suspension arm ball joints.
This 2009 black Mercedes C-Class diesel has recorded 177,971 miles. The MOT history reveals a recurring theme of suspension wear, including a failure in May 2025 for anti-roll bar linkages and suspension arm ball joints. The most recent test in August 2026 passed but flagged several concerning issues regarding brake pipe corrosion and wheel bearing play.
Specific aggregate reliability data is unavailable for this model, but the individual history shows a pattern of wear and tear consistent with high-mileage usage.
