2001 BMW M 2dr Coupe (3.2L 6cyl 5M)
Amazing car. BMW did not include the M differential or the sport mode button for political reasons. You can install the sport mode with just a wire and a button. The diff can be replaced for under $100 from a breaking yard to bring up to the pace of the E46 M3. Try a launch with sport mode on and then you will not believe it. It's a rocket ship. 12.51 quarter, bone stock.
I like the way it's so well balanced.
Do the diff and the sport mode mod. They are both very simple, and very inexpensive.
