Known issues by generation
For the E28 M5, potential issues often arise from its S38B35 engine. Timing chain and guide replacements are essential around the 100,000 to 150,000 mile mark to prevent chain rattle. The individual throttle bodies must be balanced to ensure optimal drivability, which can require specialist tuning. Common ECU failures from aged capacitors also necessitate attention, as well as possible valve cover gasket leaks. While the E28 doesn't feature Vanos, it is crucial to verify the authenticity of the BMW Motorsport build plate and ensure the engine block matches the VIN to avoid costly missteps in collector value.
Donation value by condition + generation
The collector market for the BMW M5 E28 is robust, with clean and original examples commanding significant prices. The importance of matching numbers and build plate authentication cannot be overstated, as they are key drivers of value. Original paint in iconic colors adds further desirability, while any factory color changes can be detrimental to a car's collector status. Engaging with auction houses such as RM Sotheby’s and Bring a Trailer can provide valuable insights into current market trends and necessary valuations, further underscoring the need for a qualified appraiser to document the vehicle's worth accurately.
