What we know
2.8 fails per 100 MOT tests at 9 years, against 2.3 for all class 4 vehicles tested at 9 (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.
