OK, let me get this straight.
Keeping the hard top, getting rid of the in line 6 that has proven itself over and over for a measly 4 cylinder and a dual mouse fly wheel?
BMW is going backwards on this car.
1. Get rid of the hard top crap, its a rag top car.
2. Put one awesome motor in it not two.
3. Fix the rear end, it's too fat.
4. Make a M Model
5. Call me when all the above happens.
