The BMW 2500-3.3, known internally as the E3, was BMW's flagship sedan of the early 1970s. Built from 1971-1975, it established BMW as a serious contender in the luxury car market. These models offered a superb blend of comfort, performance, and handling, setting a new standard for executive sedans.
Rust is a significant concern, particularly around the wheel arches, sills, and floor pan. The M30 engine is generally reliable, but oil leaks from the valve cover gasket and timing chain tensioner are common. Carburetor issues can plague early models, while fuel injection systems on later models may suffer from sensor or fuel pump failures. Suspension wear is also expected, affecting ride quality and handling. Electrical problems can develop with age.
WOF tips
Rust in structural areas will lead to a WOF failure. Check carefully around suspension mounting points and sills. Brake lines and hoses must be in good condition, and the braking system must function correctly. Suspension components should be inspected for excessive play. Headlight alignment and functioning lights are also critical. Windscreen must be free of obstruction causing cracks.
