📖Generation guide
E24 M6 (US) • 1987-1988
The US-market E24 M6, featuring the hand-built S38B35 engine, is known for its classic styling and dynamic performance. This two-year run is particularly prized among collectors.
M635CSi (Euro) • 1984-1989
The Euro M635CSi offers a more powerful 286hp version of the S38B35 engine. With a longer production run, these models are distinct yet share the M6’s celebrated design and engineering.
635CSi (Non-M) • 1984-1989
The 635CSi delivers a solid driving experience with the M30B35 engine. Though valued lower than M models, well-maintained examples still attract significant collector interest.
Known issues by generation
The E24 M6 and 635CSi share a lineage marked by distinctive engineering challenges. The S38B35 engine in the M6 has known timing chain issues that require preventive maintenance, typically between 100,000-150,000 miles, to avoid costly repairs. The M30B35 engine in the 635CSi, while robust, can suffer from head gasket failures and other cooling system issues. Rust is a concern for both models, particularly in vulnerable areas such as the A-pillar and rear quarter panels—especially relevant for cars in salt-belt regions versus Florida's climate. Proper maintenance and documentation are critical for preserving these vehicles' value.
Donation value by condition + generation
As classic BMWs from the analog era, the E24 M6 and M635CSi are seeing appreciating values, particularly for well-preserved, original-paint examples. The M6’s hand-built BMW Motorsport Garching heritage and matching-numbers documentation drive its market value significantly higher than non-M variants. Clean cars with original colors like Diamond Black and Cinnabar Red can command premiums over $100,000 at auctions. As such, prospective donors should ensure comprehensive records, as a qualified appraisal will be necessary for tax deductions exceeding $5,000, given the collector-tier status of these vehicles.
Donation process for this model
Donating your E24 M6 or 635CSi to Palm Motor Legacy is a meaningful way to contribute to the preservation of BMW’s Motorsport history.
