Perfect ED driver....a little too perfect. I just sold my E46 M3 vert and got a 2010 E92 M3. The E92 is so refined! Never driven a car so smooth! My wifey has an MB E500 and I think the E92 is smoother. As far a seats go, it's still a little stiff, but mine has the adjustable lumbar support which helps alot. I actually miss the rawness of the E46. From the sounds of things, I think the E9X M3 will be a perfect ED driver for you. My advice is to be prepared, once you test drive it.....the E9X M3 will own you
