Your 1987-1989 BMW M6 or 635CSi (E24) is not just a vehicle; it's a piece of automotive history, representing the pinnacle of BMW's grand-tourer heritage. These models, hand-built at the Motorsport Garching facility, are increasingly sought after in the collector market. Ideally suited for those within Wyoming, your donation helps ensure that this legacy continues while also supporting a noble cause.
The E24 chassis embodies the essence of BMW's performance ethos and elegance, particularly in its M6 variant, which features the powerful S38B35 engine. Donating your M6 or 635CSi allows you to preserve the 1980s-90s blue-chip BMW M halo legacy while providing vital support to Wheels for Wishes, helping children with critical illnesses. Remember, the manual transmission versions command a significant collector premium, reflecting their rarity and desirability.

Known issues by generation
Both the M6 and 635CSi models share some common mechanical concerns that potential donors should be aware of. The S38B35 engine in the M6 requires regular timing chain and guide replacement, especially after reaching 100-150k miles, to prevent catastrophic engine failure. On the other hand, the M30B35 engine in the non-M 635CSi is prone to head gasket failures, requiring preventative maintenance. Rust is also a recurring issue for these vehicles, particularly in salt-belt states like Wyoming, especially around the A-pillar drip rails and rocker panels. Ensuring a thorough inspection and maintenance history is vital for prospective collectors.
Donation value by condition + generation
The E24 M6 and M635CSi models hold a prestigious place in the collector car market, with values for pristine, original examples soaring between $50,000 and $130,000. Factors influencing value include matching numbers, service history, and originality, particularly with paint colors. Manual transmission models often demand a significant premium, given their rarity compared to automatics. Collectors look for complete documentation, including BMW Motorsport Garching build plate authenticity, to establish the car's history and integrity.
Donation process for this model
Donating your BMW M6 or 635CSi is a straightforward process. It's recommended to work with a qualified appraiser who specializes in vintage BMWs to ensure that the value is accurately assessed for IRS reporting, particularly using IRS Form 8283 Section B, which is essential due to the high values these vehicles can command. Enclosed transport is advised for rare models to prevent damage, while having the necessary documentation for matching numbers and original paint will strengthen your donation's credibility.
