The result of E30s becoming (arguably) very overpriced is that the remainder of BMW’s 80s collection also has risen in value. Still, the E28 and E24 represent a generally good return on an investment relative to the E30. You get classic styling, a superb driving experience, and you’re signaling your a fan while stopping short of jumping on the bandwagon. If you’re into the E24, the ones to consider are the later models with the 3.4-liter motor and E28 suspension upgrades. BMW offered three flavors of 6 in ’87 – the range-topping M6, the luxury-based L6, and the standard 635CSi. Today’s car is a high-option standard 635CSi with a few upgrades, and it sure looks great!
