Given that this is all MHO, shut up and drive. Instead of bitching about which is better than what, go drive your fucking car! Put in a stereo, change your wheels, change your oil, wash it, corner like a madman and scare the neighbors, and then write something interesting about it. If you can't write, get tutoring.
If you can't drive, and just have to bitch, there must be a reason why say, such as NOT REALLY OWNING a Z3...
As I said, just MHO, and if you don't like it, then go pound sand up your ass with a hammer.
Have a nice day.
