The BMW M6 and 635CSi (E24) are more than just remarkable vehicles; they represent an era of exceptional automotive design and engineering. Produced between 1987 and 1989, the US-market M6 and the Euro-market 635CSi are rare grand-tourers that evoke the glory days of BMW's M-heritage. With only about 5,800 examples produced worldwide, these cars command a premium in the collector market, showcasing their status as blue-chip investments with values reaching $50,000-$130,000 for pristine, original-paint examples.
At Lancaster Motor Gifts, we honor the legacy of these extraordinary machines by facilitating donations that ensure their preservation for future enthusiasts. Whether it’s a clean M6 or a well-maintained 635CSi, your contribution will play a critical role in supporting the collector community. We highly recommend a qualified appraiser with documented BMW Motorsport credentials to ensure you capture the full value of your vehicle during the donation process.

Known issues by generation
The E24 M6 and 635CSi are known for specific maintenance concerns that potential donors should be aware of. For M6 models, the S38B35 engine requires a timing-chain replacement at intervals of 100-150k miles to avoid the infamous chain-rattle. The 635CSi’s M30B35 engine is susceptible to head-gasket failures, necessitating early intervention. Additionally, rust issues at critical points like A-pillar drip rails and rear quarter-panels are common in salt-belt regions. It’s essential to maintain preventive service disciplines to uphold the vehicle’s integrity and value.
Donation value by condition + generation
The E24 M6 and 635CSi represent a blue-chip collector tier, with values driven by factors such as originality, condition, and documentation. Iron-clad authentication from BMW Motorsport Garching is mandatory for E24 M6, ensuring matching-numbers engine and build plate. Manual transmission variants command a significant premium, while original-paint examples in sought-after colors like Diamond Black and Cinnabar Red can elevate values further. A qualified appraiser's expertise is vital for accurate valuation, ensuring all IRS requirements are met for a smooth donation process.
