📖Generation guide
E24 M6 • 1987-1988
The U.S. market M6, featuring the powerful S38B35 engine, was produced in a limited run. Known for its manual-only transmission purity and iconic styling, these models are highly sought after by collectors.
M635CSi • 1984-1989
The Euro-market M635CSi boasts the same engine as the M6 but with a higher output of 286hp. Its distinct value tier reflects the rarity and exclusivity of its offerings in Europe.
635CSi • 1984-1989
The non-M variant powered by the M30B35 engine is appreciated but significantly lower in value compared to the M6, making it a different collector segment.
Known issues by generation
Both the M6 and 635CSi (E24) models come with specific maintenance considerations. The M6's S38B35 engine requires critical timing-chain and chain-guide replacements around 100-150,000 miles to avoid costly failures. Additionally, maintaining the sync of its six individual throttle bodies is essential for optimal performance. In contrast, the M30B35 engine in the 635CSi is prone to head gasket failures and requires regular cooling system maintenance. Rust is another common issue, particularly in the fender lips and rocker panels, making preventive care vital for longevity and value preservation.
