I'm trying to sell more cars from the stable so once I get my E92 this summer we only have 3 cars. Not sure if the E30 or E36 will be sold.
E36 and E46 make nice track cars. E36 is lighter, so less tire wear, and more direct steering feedback, and throttle that isn't drive by wire. E46 will have more power, more stable handling, but more expensive to maintain.
