This 2014 Mercedes-Benz SLK250 CDI has a first-time MOT pass rate of just 44.6%—significantly below the UK average of 80%—which is a genuine red flag for potential buyers and suggests reliability issues are common in this cohort. The good news is that dangerous defects are virtually absent (0%), so the failures tend to be fixable rather than safety-critical.

These cars are averaging around 56,000 miles at ten years old, which is reasonable mileage for age, yet they're still racking up an average of 0.17 failures per test with zero advisories recorded—a pattern that points to sudden, discrete problems rather than gradual wear. Before committing to one, have a pre-purchase inspection done by a Mercedes diesel specialist, as the pass rate suggests hidden costs lurk beneath the sporty exterior.
