Known issues by generation
Both the E24 M6 and 635CSi models share common issues that potential donors should be aware of. The S38B35 engine is known for timing-chain-related challenges, which can surface around 100-150k miles. Preventive maintenance is crucial to avoid costly repairs. The M30B35 engine in the 635CSi may experience head-gasket failures and requires careful monitoring of the cooling system. Rust is a notorious issue for E24 models, especially in salt-belt regions like New Haven, affecting areas such as the fender lips and trunk floor seams. Ensuring a thorough inspection and documentation of maintenance history is vital for preserving value.

The appreciating market for blue-chip BMW M models like the M6 and 635CSi means that properly maintained examples can command significant sums. Matching-numbers engines and original paint are critical value drivers, with collectors placing a premium on authenticity.
