📖Generation guide

E24 M6 • 1987-1988

The US-market M6, hand-crafted with the S38B35 engine, is known for its raw power and exhilarating driving experience. Limited to just two years, it commands a premium among collectors for its rarity and performance.

E24 M635CSi • 1984-1989

The Euro-spec M635CSi features the potent S38B35 engine, delivering 286hp. This model, while lesser-known in the US, represents the essence of BMW’s racing heritage and is a collector favorite.

E24 635CSi (non-M) • 1984-1989

The 635CSi features the M30B35 engine, a solid performer but distinct from the M6. Its lower-tier value juxtaposes the M variants, making it an entry point for enthusiasts.

Known issues by generation

While the BMW M6 and 635CSi (E24) are symbols of engineering excellence, they are not without their quirks. The S38B35 engine in the M6 requires timely timing-chain and chain-guide replacements, especially after 100k miles, to prevent catastrophic failure. Common issues include valve cover gaskets and critical throttle-body syncing for optimal performance. In contrast, the M30B35 in the 635CSi may experience head gasket failures. Therefore, proper maintenance and documentation are essential to preserve their value and driving enjoyment.

Donation value by condition + generation

The M6 and 635CSi (E24) models represent a unique tier in the collector market, with appreciating value driven by their limited production and hand-built origin. Clean, matching-numbers examples can command prices between $50k to over $100k, especially at prestigious auctions. Original paint in halo colors like Diamond Black and Cinnabar Red can significantly enhance value, while proper documentation and maintenance history solidify their place in the collector’s market.

Donation process for this model

Donating your E24 M6 or 635CSi is a straightforward process. We highly recommend consulting a qualified appraiser who specializes in vintage BMWs to ensure proper valuation and documentation for IRS Form 8283 Section B. This is crucial, as every donation generally exceeds the $5k threshold, often by a significant margin. Additionally, securing the BMW Motorsport Garching build-plate authentication and ensuring proper documentation for matching-numbers and original paint will facilitate a smoother donation experience.

Austin regional notes

Austin hosts a vibrant community of vintage BMW enthusiasts, and finding independent restorers skilled in S38 and M30 engine servicing is vital to preserving your car’s legacy. Participating in local events such as the BMW-CCA Bimmerfest enhances the experience for owners. Given Austin's milder climate compared to salt-belt regions, preservation of your E24 M6 or 635CSi is more feasible, but climate-controlled storage is still recommended to maintain its pristine condition.
