Well the RR's are always in the shop. I can't tell you how often I see them when I am at the dealer for my Maserati. There is always RR's in there for things other than normal service. That being said, SO IS THE MASERATI. LOL But I do love the SC RR's.
Cayenne Turbo is awesome, if you can get past the looks, and the srt-8 is a beast if you can get past the fit and finish. Not much info on the x's as I have never driven one, but right now, sight unseen, I'd drive the X6M...lol
