I looked at both the GranTurismo and the GranSport before settling on the later. The GranTurismo just seemed to large and heavy. It drives more like a GT than a sports car.
It's definitely a GT, although the new S version will help.
Personally, I love the GranTurismo. I've specced my ultimate version on the configurator (GranTurismo.Maserati.com) and drool was coming out of my mouth. I've looked at a couple in the flesh at dealerships, and boy, are they nice.
But it would make no sense for me to buy one. I've got the 550, which is better in most respects except the back seat. And I don't have to worry about a back seat yet...
A very mean GT at that. In August we had a drive with the Maserati Life crew and the second car in the rally was the new GT right behind a GranSport that had plenty of mods. The GT had no troubles keeping pace so I can only imagine how the S will perform.
