This is the first in a series on BMW fabled “M” line of vehicles. “M” stands for Motorsport, which is BMW’s high performance division. 1978 brought the first production “M” car, appropriately titled M1. Between then and 1981 only 456 M1 were built making it one of the rarest Bimmers. Originally, BMW commissioned exotic sports car manufacturer Lamborghini to build the car, but BMW eventually took over after 7 prototypes were built. This exotic looking speedster is the only mass produced BMW. The sleek, sexy M1 begins the long storied tradition of BMW’s high performance “M” cars.
