Known issues by generation
Both the E24 M6 and M635CSi models come with their share of known issues that potential donors should be aware of. The S38B35 engine is notorious for its timing chain and chain guide replacements, which are essential at the 100,000 to 150,000-mile mark. Other notable concerns include valve cover gasket leaks and throttle body synchronization. In contrast, the M30B35 engine found in the non-M 635CSi is prone to head gasket failures and cooling system issues. Rust is also a significant concern for all E24 models, particularly in salt-belt regions like Buffalo, warranting careful inspection and preventive maintenance to preserve their integrity.
Donation value by condition + generation
The market for E24 M6 and M635CSi vehicles has shown an impressive appreciation in value, making them attractive to collectors. Clean, original-paint examples can fetch between $50,000 to $130,000 at prestigious auctions. The emphasis on matching-numbers engine blocks and the BMW Motorsport Garching build-plate authentication is paramount for value preservation.

Engaging with expert appraisers and documenting the vehicle's history are essential steps to maximize the donation's impact.
