Was it the V8 R8? If so im not suprised, its not that special (in comparison to the V10 R8)
GTR is just quick, nothing else really. Best car would be a 911 for her as an overall package. Maserati is nice but you would have to love it and they are not very fast.
A bently continental would be a good shout.
Other end of the spectrum: Range Rover Sport
