The 2001 and 2002 M roadsters are unique in their absolute driving performance. The engine is sublime and the car can out run just about anything on the road. From a roll, from a launch, or on the freeway it just runs away. Most everyone underestimates the car and I have yet to see a car (even new models of corvette, SRT8s, camaros, etc) that can even keep close. The car can break the tires free shifting into any gear but is so balanced that there is no loss of control or fishtailing. If you think your current car is fast and handles well you should drive one of these to compare.
The motor has torque and HP at every RPM. Can drop it in 3rd at 90 and spin the tires. 50/50 weight balance.
The seats are tight and hold you in firmly, great for spirited driving but less so for daily driving.
