2005 Mercedes-Benz C 2.1L Diesel · SF55 YRZ

The most recent MOT test on 2026-07-26 shows this 2005 Mercedes-Benz C has been driven just 103 miles since its last failure on 2025-04-08, with no defects recorded in either the April 2025 or April 2024 tests. The pattern of consecutive passes and failures—each spaced roughly 12 months apart—suggests a stable but inconsistent maintenance cycle rather than worsening deterioration. The absence of advisories or recurring faults across five tests implies the vehicle has not suffered from persistent mechanical issues, though the repeated failures without recorded defects indicate either a high standard of pre-test repairs or a tester’s reluctance to note minor non-compliances. The recorded mileage of 106,300 miles over 21 years—approximately 5,062 miles annually—is unusually low for a vehicle of this age, suggesting prolonged periods of limited use. The gaps between tests (around 12 months) align with this pattern, with no evidence of rapid mileage accumulation or aggressive driving. The lack of mileage spikes between failures also reduces suspicion of deferred maintenance due to high usage, though the low annual mileage does not guarantee longevity of wear items like suspension bushes or brake calipers. Given the absence of recorded defects, a buyer should prioritise a thorough inspection of high-wear components that often fail without obvious warning signs. Focus on the suspension—particularly rear coil springs and bushes—for signs of fatigue or corrosion, as older Mercedes-Benz models are prone to bush deterioration even with low mileage. The braking system warrants scrutiny, especially rear calipers and discs, given the repeated failures; binding or uneven wear could indicate past neglect or improper servicing. Structural integrity should also be checked, particularly around the wheel arches and sills, where corrosion can compromise safety without affecting MOT passability. Finally, verify the condition of the exhaust system, as catalytic converter failures are common in this model and often go unrecorded unless they cause emissions failures.
