Parts for the Mercedes-Benz C-Class C 55 AMG

Known issues

A significant common issue is rust -- focus your inspection on the wheel arches, door sills, and underbody. Also, look for electrical problems (ABS, BAS, ESP), engine oil leaks, and worn suspension components (especially ball joints and bushings). Diesel particulate filters (DPFs, if fitted) can become problematic, especially if the vehicle is primarily used for short trips.

WOF tips

A WOF inspection will pay close attention to excessive rust affecting structural integrity (chassis, suspension components, and brake lines). Ensure suspension components are correctly attached and haven't deteriorated. Examine the brake lines for corrosion, and check the operation of all lights and SRS (airbag) system readiness.
