What happens

Symptom. Bubbling paint at the rear arches and around the boot lid or tailgate, and rust in the spare wheel well.

Cause. This generation was built during Mercedes' worst period for corrosion protection, and cars in salted climates suffer. Later cars are better than early ones, but the body is worth more attention here than on a W212.

How to check it

Static checks

Look along the rear arches and the boot or tailgate seams in good light, lift the boot floor, and check underneath for previous repair.

Engine off, ideally on a lift.

The last column is the point. The same repair is an inconvenience on one variant and a reason to scrap the car on another. A failure costing a quarter of the vehicle's value changes the purchase decision regardless of how rare it is.
