If you want a classic M series BMW, you can’t go wrong with an M1. They were built between 1978 and 1981, with a top speed of 260 km/h and zero to 100 km/h in 5.6 seconds.
The interesting fact with the M1 BMW was the fact that they were initially designed and built by Lamborghini. Lambo couldn’t honor their contract and so the M1 was then assembled by BMW with the chassis and bodies coming from Italy. The body itself was designed by Giorgetto Giugiaro, another Italian.
When you look at it, there wasn’t that much BMW in it after all.
