What a 28-year-old car fails on

A 1998 car is 28 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 1998 Jaguar Xk8 the average at test was 90,429 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 2005 at 81%, and the weakest in our data is 2000 at 73.2%. That 7.8 point spread across the model's life is why comparing a 1998 car against a newer one tells you very little.
