The BMW M5 E28 represents an iconic era in automotive history, combining performance and luxury in a hand-built sedan that set the standard for all M cars to follow. Produced between 1985 and 1988, this first-generation M5 is powered by the legendary S38B35 engine, a 3.5L inline-six derived from the M1 supercar, capable of producing 256hp in US specs. As one of only 2,191 examples produced worldwide, its rarity has solidified its status within the blue-chip collector market, where pristine models fetch $80,000 to $150,000.
Owning an E28 M5 is not just about the car; it’s about being part of a meticulously preserved lineage that celebrates the engineering brilliance of BMW Motorsport. Our donors help maintain the value of these remarkable machines through preventive maintenance and restoration efforts.

Known issues by generation
The E28 M5 is celebrated but does have its quirks.

Further, maintaining the six individual throttle bodies is crucial for optimal performance. The Bosch Motronic ML 1.x ECU may develop capacitor failures, and rust is a common concern in various regions, especially along fender lips and rocker panels. Original-paint integrity is paramount for collectors, and any deviation may impact value significantly.
