This 2006 Mercedes C220 CDI has a first-time pass rate of just 41%, nearly half the UK average of 80%, making it a genuinely unreliable proposition by MOT standards. The good news is that dangerous defects are absent from this dataset, so failures tend to be fixable rather than safety-critical, though at 0.98 average failures per vehicle, problems are still the norm rather than the exception.
At 152,835 miles on average, these cars have been driven hard but not abused for their age, and the complete absence of advisories suggests owners either fix issues promptly or aren't reporting minor concerns. Before buying one, budget for repairs on the assumption it will fail its MOT—have a pre-purchase inspection focus on the engine management system, suspension, and emissions equipment, which are typical failure points on high-mileage diesel Mercedes of this era.
