Its unassuming appearance and critically acclaimed performance made it popular among car enthusiasts, and it is widely regarded as a pioneer of the modern sports sedan. While the European version featured a high-performance engine derived from the BMW M1, the North American model used a different powertrain and was offered only for the 1988 model year. With just 2,241 cars built, this first-generation M5 remains one of the rarest M cars in BMW’s history. • Engine: 3.5-liter inline-6 • Top Speed: 147 mph • Horsepower: 256 hp • Price When New: $48,270 • Approx.
