📖Generation guide

E24 M6 (US) • 1987-1988

The US-market M6 features the S38B35 engine producing 256hp, a rare collector's item with only 2 years of production. Manual transmission examples are particularly sought after.

M635CSi (Euro) • 1984-1989

Sharing the same engine platform as the M6 but with 286hp, the Euro-spec M635CSi is a coveted vehicle for collectors, especially with verified provenance.

635CSi (Non-M) • 1984-1989

The non-M variant comes with the M30B35 engine producing 182hp. While less valuable than its M counterparts, it still holds collectible appeal.

Known issues by generation

Each generation of the M6 and 635CSi has unique considerations for potential donors. The S38B35 engine often requires timing-chain and guide replacements by 100-150k miles, a crucial preventive measure for longevity. The M30B35 variant is prone to head-gasket failures and other cooling system issues. Both engines have specific tuning requirements and may suffer from rust in common areas due to age. It's important for owners to maintain thorough documentation of any work performed, especially for collector value.

Donation value by condition + generation

As part of the appreciating collector market, the BMW M6 and 635CSi models command significant value, particularly if they are in original, matching-numbers condition. M6 examples can reach $70-130K at auctions like RM Sotheby's and Pebble Beach Concours, while clean M635CSi models are also increasingly sought after. Original paint and documented service history are critical in determining value; factory color changes can severely affect collectibility. Engaging a qualified appraiser is essential for any donation to ensure you receive the full tax benefit.
