The BMW M6 and 635CSi (E24) represent the zenith of 1980s grand-touring performance, combining a thrilling driving experience with elegance that is difficult to match. Produced from 1976 to 1989, the E24 chassis solidified its place in automotive history with its muscular design and robust performance, particularly in the US-market M6 (1987-1988) and its European counterpart, the M635CSi. With a production run of approximately 5,800 units, these vehicles have evolved into coveted collector items, revered for their hand-built BMW Motorsport craftsmanship and appreciating values ranging from $50,000 to over $130,000 for pristine examples.
Preserving these classic machines is vital, and your donation to Gem City Rides not only keeps the spirit of the M6 and 635CSi alive but also honors the legacy of BMW's engineering excellence. Ensuring that these vehicles receive the necessary preventive maintenance and care is essential for their continued appreciation. We urge owners in Dayton to consider donating their well-preserved M6 or 635CSi, which will support our mission to celebrate and restore these iconic vehicles while emphasizing the importance of proper maintenance and documentation.
