The BMW M5 E28, produced between 1985 and 1988, stands as the original sports sedan that laid the foundation for future M models. With only 2,191 units produced worldwide, this iconic vehicle showcases the unmatched craftsmanship of the hand-built BMW Motorsport Garching factory. As a quintessential representation of the analog-era driving experience, the E28 M5 is highly revered within the collector community, particularly for its manual-only, pure enthusiast focus.
Owning a classic M5 E28 not only offers thrilling performance with its S38B35 engine, derived from the legendary M1 supercar, but also represents a sound investment. With clean, low-mileage examples garnering values between $80,000 to $150,000, preserving these vehicles is essential. We strongly encourage potential donors to engage qualified appraisers familiar with vintage BMWs to assess and validate their vehicles before donation.
