G35's are nice. IS300's are luxury and sport combined, that's why i got one. I love mine because it has leather seats with cloth on the middle so that it looks nice and its comfortable. You don't get swamp ass from the leather on hot days. 
It has pretty decent performance and if fixed up the right day can pull all the ******es
