Used 1988 BMW M5 Base

When BMW introduced the E28 M5, it quietly redefined what a performance sedan could be. Hand-assembled by BMW Motorsport GmbH, the U.S.-spec car was powered by the S38B35 3.5-liter inline-six, a close relative of the legendary M88 engine used in the European M1. Delivering 256 horsepower and paired exclusively with a 5-speed manual gearbox, the E28 M5 combined understated styling with motorsport engineering, creating the template for every high-performance four-door BMW that followed. Its mechanical purity and driver engagement remain the benchmark for the M5 lineage to this day.This 1988 M5 shows 83,704 miles and presents as a remarkably honest, well-preserved example. Finished in its original black exterior over Natural leather, it retains the refined, purposeful look that defined BMW Motorsport’s first U.S.-market sedan. The paint displays even gloss with only minor patina consistent with age, and the interior remains clean and supple, with excellent leather condition and intact factory switchgear.Originally a California car through 2018, this M5 was first sold by Enthusiast Auto Group in 2018 to a local client who continued to maintain it under our supervision throughout his ownership. Having benefitted from consistent care and detailed documentation, it returns to our facility with a fully traceable history and service continuity that few E28s enjoy.In preparation for presentation and sale, this E28 received the Enthusiast Auto Group’s standard intake evaluation and preservation process, a detailed multi-point inspection, verification of fluids, systems, and components, and light recommissioning consistent with EAG’s delivery standards. All work will be carried out to maintain the car’s originality and ensure mechanical integrity for its next caretaker.Mechanically, this M5 remains tight and confident, steering response is immediate, clutch engagement is solid, and the signature inline-six sound is unmistakable. The car feels cohesive and balanced, offering the mechanical intimacy that modern cars have long since lost.
