This 2013 SLK250 AMG is a significantly weaker MOT performer than the UK average, with a first-time pass rate of just 49% against the national 80%—a stark 31-point gap that makes it a genuine reliability concern for buyers. The good news is that dangerous defects are non-existent in this cohort, so safety isn't the issue; the problem is recurrent minor failures dragging down the pass rate.

At 61,200 miles median mileage, these cars are relatively lightly used for their age, yet they're still failing MOT tests roughly one in two times, averaging 0.33 failures per vehicle. The diesel engine doesn't help matters—the 254 diesel examples in this dataset show a 48% pass rate, suggesting the engine or emissions systems are the weak point. If you're considering this model, budget for a pre-purchase inspection by a Mercedes specialist and factor in ongoing remedial work; this isn't a carefree used buy.
