This 2012 SLK250 is a reliability concern: it passes MOT first time just 41.2% of the time, nearly half the UK average of 80%, and the diesel variant (40.7% pass rate across 109 vehicles) shows no meaningful advantage. The good news is that dangerous defects are absent from this cohort, so failures tend toward manageable repairs rather than safety risks.

At 68,000 miles on average, these cars are driven moderately for their age, yet they're still racking up 0.31 failures per vehicle on test, suggesting age-related wear rather than abuse. If you're considering one, budget for pre-purchase inspection by a Mercedes specialist—the MOT pattern indicates you'll likely need suspension, brake, or emissions work within the first year of ownership.
