BODYWORK

W463s from the 1990s are particularly prone to rust, mainly around the rear lights, windows and bumpers. If all looks clean, dig deeper to make sure corrosion hasn’t just been filled and painted. Mechanical components and chassis elements may have sustained damage during off-road expeditions. Later cars can suffer from leaky and malfunctioning sunroofs as a result of blocked drain holes, and corrosion here can cost thousands to repair.
