What the MOT tests show

What we know

1.2 fails per 100 MOT tests at 5 years, against 0.5 for all class 4 vehicles tested at 5 (all test years). That is about average.

Why it matters

A body and structure fail stops the car passing until it is fixed.

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.

The Mercedes-Benz X-Class is a commercial or van-based vehicle: it is compared with all class 4 vehicles, cars and vans together, so part of any difference can come from how vans are used.
