While most serious reviews of the M3 tells us that the car is really complete, the real inspiring driving is done at the limit. That is a shame I think... but then again since it is so much faster than the previous M3 it's bound to have its limits set further up. This makes driving at the limit on ordinary roads not only hard, but very dangeroud since you are not alone.
Just look at what John Barker wrote in his long term test of the M3.

In any case the M3 seems to be a truly great car, Auto Express on the other hand thinks the 535d is the better of their two BMWs and I think that tells alot about their preferences when it comes to cars.
