📖Generation guide
E24 M6 • 1987-1988
The US-market M6 features a hand-built S38B35 3.5L engine producing 256hp. This two-year limited production run makes it particularly valuable in the collector market.
Euro M635CSi • 1984-1989
This variant boasts a stronger S38B35 3.5L engine with 286hp, offering a richer driving experience. However, grey-market documentation is essential for compliance.
635CSi (non-M) • 1984-1989
With a lower M30B35 3.5L engine producing 182hp, these models are valued less than their M counterparts but still hold significance as grand tourers.
Known issues by generation
Owners of the E24 M6 and 635CSi should be aware of certain maintenance issues that can arise over time. The S38B35 engine in the M6 is notable for its timing chain and guide replacement needs around the 100,000 to 150,000-mile mark to prevent issues such as chain rattle. Additionally, the M30B35 engine in the 635CSi may experience head gasket failures, alongside the need for thorough cooling system maintenance. Rust is a chronic concern, particularly in salt-belt regions, affecting the fender lips and rocker panel seams. Regular preventive maintenance is crucial to ensure the longevity and performance of these remarkable automobiles.
Donation value by condition + generation
The collector value of the BMW M6 and 635CSi E24 models remains robust, driven by their heritage as hand-built masterpieces from BMW Motorsport Garching. Original-paint examples in halo colors like Diamond Black and Cinnabar Red command a premium, with prices ranging from $50,000 to over $100,000, especially for well-documented, matching-numbers cars. Manual transmission variants can see significant additional value, further reflecting the desire for authentic driving experiences. Documentation from recognized appraisers such as Hagerty and auction houses is vital for establishing fair market value.
Donation process for this model
Donating your BMW M6 or 635CSi E24 is a straightforward yet rewarding process. Heart Wheels strongly recommends involving a qualified appraiser with documented credentials in vintage BMW or Motorsport expertise to establish the vehicle's value. IRS Form 8283 Section B is heavily applicable, as the value of these cars often exceeds the $5,000 threshold. We advise enclosed transport for high-value, original-condition examples to ensure their protection during the donation process. For grey-market models, ensure all federal compliance documentation is in place.
