Had an 05 Acura TL. Traded it in for the 2006 G35. MIGHT have kept it if it were rear wheel drive. But needed something sportier. The G35 fits the bill. Almost got the 350Z, but I wanted something a little bigger with a usable back seat and a less harsh ride. I wish it had better mileage. But 300 horses gotta be fed. If you're thinking of buying one, the G35 won't disappoint. Truly a great car. I only had the car for 2 weeks. I'll do a follow up in 6 mos and tell you if I still luv it as much.
Navigation is very cool. Love the birds-eye view. It's way better than the top-down view. Ride is awesome. Firm, but compliant. Even with the sports suspension.
Room for taller drivers. I'm 6ft and barely have headroom with the seats lowered all the way. More comfortable seats. More flowing, integrated dash. Smoother shifter, but that's being nitpicky. Better gas mileage.
