In the last few years we have owned a 2000 Audi S4, 2000 C5 Vette, 2003 M3, Jetta GLI, and now have the 2004 GTO and a Mini S.
So far, I would have to say that as a daily driver, the GTO is probably one of the best of the bunch. The S4 was quick but the suspension was too soft and it tended too much towards the luxury side. The C5 was great but I always felt the handling was a bit crudish (those transverse leaf springs just get to me), the M3 was pretty awesome in power, handling and breaking but for my wife and me it just seemed like to really get the real enjoyment out of it you had to be driving 8/10ths or 9/10ths all the time. And, it was a bit rugged in the shifting, rear end.....a true race car on the street and it acted that way. The Mini S is just a plain hoot. It is very different than the other cars but a handling fool and with the supercharger plus mods made to it quite quick. The GTO is smooth and basically, a 4 seat Vette that is a bit more sophisticated all around while giving up little in performance. A grand tourer in the best sense.
