The 1996 Mercedes-Benz SLK has a first-time MOT pass rate of 76.2%, sitting below the UK average of 80%, and a concerning 25.3% of examples have recorded dangerous defects—something to take seriously when inspecting a prospective purchase. The petrol-only specification of this era means there's no fuel-type variance to consider, but the relatively high dangerous defect rate suggests these 27-year-old cars demand thorough pre-purchase checks.

With a median mileage of 88,520 miles, these SLKs are reasonably low-mileage for their age, yet they're still generating an average of 3.89 failures and 21.2 advisories per test, indicating age-related wear rather than neglect. Focus your inspection on brake systems, suspension, and the roof mechanism when evaluating one—these numbers suggest those are where most issues emerge.

We have limited data for the 1996 Mercedes Benz Slk — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
