What happens
Symptom. A knock from the rear over bumps, vague handling, and uneven tyre wear at the back.
Cause. The rear multi-link bushes wear, and cars that carried weight or covered high mileage go first. Corrosion of the subframe is a second issue in salted climates.
How to check it
Static checks
On a ramp, lever the rear bushes for splitting and look at the subframe for corrosion, then listen for a knock over rough roads.
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.
