What a 23-year-old car fails on

A 2003 car is 23 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 2003 Mazda B Series the average at test was 122,110 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.

2003 is the strongest year on record for this model at 66.1%, ahead of every other year we hold data for.
