The 1989 BMW 6 Series is part of the first generation that spans from 1976 to 1989. It comes in one trim level – the 635CSi. Under the hood, it boasts an impressive M30B35 3.5-liter inline-six engine generating 208 horsepower, mated to either a four-speed automatic or a five-speed manual transmission. Notable features for the year include an anti-lock brake system, a choice between RWD coupé and convertible models, and an available M Sport suspension. Inside, the car lures with a premium leather interior and ample luxury features. While it lacks the advanced technology and infotainment systems of more modern cars, the '89 6 Series is highly valued for its timeless design, classic driving dynamics, and BMW's knack for engineering.
