Should I check the MOT history before buying a 2003 Mercedes C220 CDI Avantgde SE A?

This 2003 Mercedes C220 CDI is a serious reliability concern — only 36% pass the MOT first time, nearly half the UK average of 80%. The near-complete absence of advisories (0.0 per vehicle) combined with a 0% dangerous defect rate suggests these cars either fail catastrophically or pass cleanly, with little middle ground.

At 164,000 miles median, these examples have typical mileage for their age, yet the 0.38 average failures per vehicle indicates systemic issues rather than random wear. If you're considering this model, have a pre-purchase inspection focus on the diesel engine and emissions systems, as first-time pass rates this low usually point to specific component weaknesses in this generation.
