Pass rates fall as cars age, so the only fair comparison for a 2004 car is other cars of the same age. The full run for the MG Zt:

What a 22-year-old car fails on

A 2004 car is 22 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 and into the range where cambelts and water pumps are due if they have not already been done, so ask for the service history rather than take the mileage on trust. On a 2004 MG Zt the average at test was 97,726 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.

2004 is the strongest year on record for this model at 72.9%, ahead of every other year we hold data for.
