INTERIOR & ELECTRICS
There’s plenty inside an E46 to repair or replace so avoid cars that show noticeable trim wear or faded plastics. Make sure that electric seat adjusters have not frozen from lack of use and that the airconditioner delivers cold air. Some A/C parts can only be sourced from BMW and are expensive. One feature of these cars was the special and quite complex sound system fitted to later models. Take some time to have the vendor explain how (and if) the various features work. Do the same with the multifunction dash display screen. Replacement headlights are expensive; check for frosted reflectors or cracks.
