I must admit, when I went to Sly's late last year, he removed a GTR from the workshop to do some work on my zed, and it made it look small! (it was for sale too at some price north of £30,000). The presence those things have on the road is immense. Love to own one eventually.
Odd car admittedly, they will wipe the floor with most cars whilst being "normal", get them in race mode and its a different animal but (a standard one at least) doesn't feel as raw as a traditional sports car, but that's the entire point. The car is stuffed to the brim with electronics to make it 1. as fast as possible and 2. as easy to drive as possible.
