The BMW M6 and 635CSi (E24) represent the pinnacle of German engineering and performance from the late 1980s. With only around 5,800 units produced worldwide, these vehicles have become highly sought-after collector's items, particularly in Maryland, where enthusiasts appreciate their rich history. Donating your M6 or 635CSi not only helps preserve this esteemed model but also supports Chesapeake Chariots in our mission to promote automotive heritage.
These models feature the renowned S38B35 engine, synonymous with raw power and impeccable handling, and come equipped with the option of either a Getrag 5-speed manual or ZF 4-speed automatic transmission. Their status as appreciating assets in the classic car market, often reaching values of $50,000 to $100,000 or more, makes them perfect candidates for donation. We encourage you to maintain a preventive maintenance philosophy and involve qualified appraisers to ensure your vehicle's value is properly documented.

Known issues by generation
Common issues for the E24 models include timing chain and guide replacements on the S38B35 engine, which is crucial for performance and longevity. Owners should be aware of the potential for rust around critical areas such as fender lips and rocker panels, particularly in the salt-belt regions of Maryland. Ensuring proper maintenance and timely service can mitigate these concerns, preserving the classic appeal and value of your M6 or 635CSi.
Donation value by condition + generation
The collector market for E24 models is driven by their hand-built BMW Motorsport Garching heritage, with matching-numbers authentication being essential for value appreciation. Cars in original paint with documented service history command a premium, especially the M6 models with the manual transmission, which can attract $10,000-$25,000 more than their automatic counterparts. It’s vital to engage a qualified appraiser to ascertain and document your vehicle's value, particularly for IRS purposes under Form 8283 Section B.
Donation process for this model
Donating your M6 or 635CSi is a straightforward process, but we highly recommend working with a qualified appraiser who has certified BMW Motorsport or vintage M credentials. Each donation typically exceeds the $5,000 threshold, making IRS Form 8283 Section B critical for documentation. Secure enclosed transport for original-paint examples to ensure their pristine condition during transit, and validate your vehicle's authenticity with the BMW Motorsport Garching build plate.
