CHECK IT CLOSE
specific things to inspect and negotiate

What goes wrong

If equipped with AIRMATIC: struts, valve blocks, and compressors age out, a car that sags overnight or sits low on one corner is telling you. Coil-spring cars are exempt.

Federal record for the 2012 Mercedes-Benz E-Class, pulled from NHTSA when this page was built:
233 owner complaints on file , most-reported: AIR BAGS (91) · FUEL/PROPULSION SYSTEM (21) · SUSPENSION (15).
0 safety recalls listed.
Complaint volume tracks how many were sold as well as how they held up , read it as a pattern, not a score. Counts change; confirm live at nhtsa.gov or by running the free check below.
Rough cost: $1,200-$2,000 per corner · $800+ compressor. Broad estimates , labor rates and parts vary widely by region and shop.

What to do about it

Before you hand over cash: Look at the car’s stance the moment you arrive (before the seller starts it and it re-levels). Ask them to leave it parked overnight before your showing if you can. Sag = suspension money incoming.

Whatever you find, a $100-150 pre-purchase inspection by an independent mechanic is the cheapest money you’ll spend on any used car , including this one.
