Every Lexus Is250 model year

Pass rates fall as cars age, so the only fair comparison for a 2006 car is other cars of the same age. The full run for the Lexus Is250:

What this means if you are buying a 2006 Is250

The 2006 is a weaker year for this model, passing 4.3 points less often than the Lexus Is250 average. Some of that is simply age, so compare it against the 2006 figure for all cars above rather than against newer examples. 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 20-year-old car fails on

A 2006 car is 20 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 high mileage, so timing belts, clutches, suspension bushes and corrosion are the items worth budgeting for rather than the MOT itself. On a 2006 Lexus Is250 the average at test was 113,776 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 2012 at 89%, and the weakest in our data is 2006 at 76.3%. That 12.7 point spread across the model's life is why comparing a 2006 car against a newer one tells you very little.
