A hallmark of the 1990s era of BTCC, arguably one of the more revered periods of the series, the E30 M3 cemented itself as the car to have on the road thanks to the racing prowess of the race cars. A key player in the thrills-and-spills of the 1990s, the M3 is BTCC royalty and was driven to Championship wins in 1988 and 1991.
