G35's are amazing cars! We had a 2006 X (AWD) for years as the family car until some idiot took us off the highway, but we all walked away. I came close to buying it back from the insurance company because it handled so well and was fun to drive. Maintenance is easy too because its just a Nissan underneath and is really a 4 door 350z. Either a daily driver or gut it for a track toy, can't go wrong!
