Went to the first centre in Reading a while back and test drove a G37S. Very nice car, good toys and decent handling. Not on a 370z's level, but if I was after more cruiser than sports car, it would have been on the short list for sure. Same engine and drive train as the 370z so sure a bit of UpRev magic would have made the engine/drive train side of things better as it was more sluggish than the 370z, didnt feel as urgent. Lovely armchair seats though, great if you do a lot of miles.
The missus wants their new baby 4x4, she works opposite the Infiniti, Audi and Nissan garage in Reading so is constantly changing her mind over what she wants next
