I guess it is time to protect the M3 a little bit. I only know the old E30 M3 because I had a Group N M3 race car I used on my favorite track , the old Nuerburgring. With a dry track I would be willing to take on an A4 with the same power to weight ratio any time! For an every day car to get me to work at all weather conditions I would choose the A4 naturally.
