Rare 1988 BMW E28 M5 For Sale: The Original Super Sedan, Enhanced
A truly exceptional piece of automotive history, a rare 1988 BMW E28 M5, is currently available on Bring a Trailer. This is the car that defined the high-performance luxury sedan segment, earning its status as the original super sedan masterpiece. With only 1,239 examples originally imported to the U.S., each surviving E28 M5 is increasingly sought after. This particular model stands out with just 59,000 miles on the odometer, a clean presentation, and thoughtful, period-correct performance upgrades.
The M1-Derived Heart with an Extra Punch
At the core of this legend is the renowned M88 3.5-liter inline-six engine, directly related to the powertrain found in the iconic BMW M1 supercar. While U.S.-spec M5s were initially rated at 256 hp, this engine received a significant upgrade in 1998, being rebuilt and enlarged to 3.6 liters by specialists at Korman Autoworks. This modification is designed to restore and even exceed the power of the European-spec models, delivering enhanced horsepower and torque for a spicier driving experience. Recent maintenance, including a new water pump and ignition components, ensures its mechanical readiness.
Classic Luxury Meets Refined Dynamics
This E28 M5 isn’t just about raw power; it also boasts a comprehensive list of 1980s luxury features, including heated power sport seats, cruise control, and air conditioning. Visually, it retains its timeless appeal with the iconic 16-inch basketweave BBS wheels. The driving dynamics have been subtly updated with Bilstein shocks and H&R lowering springs, which provide a more modern, sharper handling feel while maintaining the sophisticated ride quality expected of a premium sedan from its era. The replaced Getrag five-speed manual transmission and limited-slip differential promise precise power delivery to the road.
Appreciating Asset: A Compelling Value
Originally priced around $48,000 in 1988, the E28 M5 is now a rapidly appreciating classic. Clean examples typically fetch between $40,000 and $80,000, with pristine models commanding six figures. Currently, with six days left on the Bring a Trailer auction, the bid stands at $32,500, presenting a potentially compelling value for enthusiasts. Its recent sale on the same platform in April 2025 and subsequent acquisition by a California dealer suggest strong market confidence in its quality. Many consider the E28 M5 to be the greatest M5 ever built—a high-performance sedan that was the fastest of its time, weighing almost half of today’s 5,390-pound M5.
