As Wiggum said, GTA4 is not really a driving game, but it looks incredible in HD and you do find alot of your time spent behind the wheels of cars such as Dodge Chargers, Chevy Camaro's, Porsche 911's, Aston Martin's and Ferrari's. Oh! And the Infernus in that game is a complete rip off of the Zonda I say. Gorgeous game though, and really fun on XBox Live!
