The original super saloon came in the from of the BMW M5
The first fully M-Sport 5-Series repeated the formula of stuffing a powerful engine under the bonnet of the well-proportioned 5-Series. This time, the full-fat 24-valve 286bhp M1 engine created a super-saloon par excellence, and unlike the M535i – which looked every bit the road racer – the M5 was discreet to the point of anonymity. Canny owners even removed the badges. With just 187 RHD cars built, the E28 M5 has now gained legend status, and values, according to Dan Norris at Munich Legends, continue to head skyward.
