What the MOT tests show

What we know

1.3 fails per 100 MOT tests at 6 years, against 0.8 for all class 4 vehicles tested at 6 (all test years). That is about average.

Why it matters

A body and structure fail stops the car passing until it is fixed; the most common one is rated major by DVSA.

What to check

Look under the sills, jacking points and rear subframe for rot, bubbling or fresh underseal over a repair, and check every door, bonnet and boot shuts properly.
