Well just a helluva question! I had a 533ci built and it has its plusses and minuses. First of all....good thing I still have about 1/2" of room between the engine and the compartment side walls at the corners, cuz it DO have some idle vibrate....and YES....overheating was the order of the day until I put one helluva puller fan into the shroud!! It lopes like it means business with a modest cam in it.... I'm beginning to wonder...since I have no track experience and drive it strictly street, whether sometimes it might be more fun to drive a slower car fast than a very fast car slow...know what I mean? I can walk this dog, but I can almost never let it off its leash haha!
......AND my wife just LOVES the car.
FUN though.... and all the oooohs and aaaaahhhhs that your ego can stand.
Regards,
Dirk
