...the '08 Infinit G-37? I would like to know about the power train and track performance for the both of them. Which car would come out on top (includeing priceing).

Infinity G-37 there's no doubt about that. It looks better and it's not made by Toyota! The G-37 is a couple and the Is 350 is a sedan. Do you mean the G-35 Sedan? The Infinity has more power on the coupe with 330 horses compared to 306. The G-35 Sedan has 306 horse power same as the Lexus. The G-37 and G-35 get better gas mileage then the Lexus. So I'm going to go with the Infinity on this one.
