E24 M6 • 1987-1988
The US-market M6 offers the iconic S38B35 engine with 256hp, distinguished by its manual transmission. This model holds a unique position in the collector's market due to its limited production and performance pedigree.
Euro M635CSi • 1984-1989
Featuring the more powerful S38B35 with 286hp, the Euro M635CSi shares many components with the M6 but carries a distinct value tier due to its European heritage and availability.
635CSi (Non-M) • 1984-1989
The non-M variant comes with the M30B35 engine, producing 182hp. While it offers a different driving experience, it is considered a lower-tier collector item compared to the M models.
