Known issues by generation
Both the E24 M6 and 635CSi share some common issues typical of their era. The M6, with its S38B35 engine, requires timing chain and guide replacements to avoid chain rattle at intervals of 100-150k miles. The M30B35 engine in the 635CSi is predisposed to head gasket failures, making preventive maintenance critical. Owners should also be aware of the importance of synchronizing the individual throttle bodies on the S38 for optimal performance. Lastly, rust is a known challenge, particularly in regions with harsher climates, making careful inspection a must for preserving these classic models.
Donation value by condition + generation
The E24 M6 and M635CSi represent prime examples of appreciating automotive investments, with clean, original-paint cars fetching between $50,000 and $130,000 at auction. The hand-built aspect of these vehicles, combined with their documented maintenance history, including matching-numbers engine blocks and factory build-plate authenticity, is vital for collectors seeking to maintain value. Manual transmission variants hold a significant premium over automatics, further increasing their desirability in the market. Original-paint examples in rare halo colors command the highest prices, while documentation of preventive maintenance and service records can significantly enhance value for potential collectors.
Donation process for this model
Donating your BMW M6 or 635CSi is not just a generous act; it also involves following specific guidelines to ensure the highest appraisal values. We strongly recommend working with a qualified appraiser who specializes in BMW motorsport vehicles to prepare for IRS Form 8283 Section B, as every donation crosses the $5,000 threshold by a substantial margin. Your vehicle's authentication through the BMW Motorsport Garching build-plate is essential, along with maintaining documented matching-numbers engine block evidence. For European models, ensure compliance with federal requirements, including grey-market documentation. Secure transport services are also recommended for valuable examples to preserve their integrity during the donation process.
Tampa regional notes

Local events such as Bimmerfest and the Legends of the Autobahn concours offer excellent networking opportunities for enthusiasts to connect and share knowledge. Given the sun-belt climate, preserving these vehicles typically involves less rust-related damage compared to vehicles from salt-belt regions. Additionally, climate-controlled storage options are available to help maintain the integrity of low-mileage examples.
