Pass rates fall as cars age, so the only fair comparison for a 2002 car is other cars of the same age. The full run for the Mercedes-Benz Slk:

What this means if you are buying a 2002 Slk

The 2002 sits close to the Mercedes-Benz Slk average, so there is no strong model-year signal either way. Judge the individual car on its own history. Check the exact car with the free MOT history checker before you buy, and run its VIN and mileage through our free VIN decoder and clocking check.

What a 24-year-old car fails on

A 2002 car is 24 years old now, and age drives the failure mix more than the badge does. Across all cars tested, these are the categories that actually cause failures:

  • Lights and electrical: 10.36% of all cars tested
  • Suspension: 8.65% of all cars tested
  • Tyres: 6.23% of all cars tested
  • Brakes: 6.1% of all cars tested
  • Visibility: wipers, washers, glass: 4.65% of all cars tested
  • Body, chassis and structure: 3.18% of all cars tested

That is above average, the point where suspension bushes, drop links and exhaust corrosion start showing up as advisories before they become failures. On a 2002 Mercedes-Benz Slk the average at test was 86,605 miles, so treat anything far above that as a car that has worked harder than its peers, and anything far below as one worth checking for the faults that come from standing still.

The strongest year for this model is 2016 at 83.9%, and the weakest in our data is 2004 at 70%. That 13.9 point spread across the model's life is why comparing a 2002 car against a newer one tells you very little.
