Well my wife has a 2002 Infiniti I35. The carpet, right where the floor mat sits, develpoped a cut. The dealer agrees to warranty it (which was a surprise to me), and gives my wife a 2004 G35 sedan for a loaner. It has all wheel drive also. I took it out on Monday night. First impression, seats are extremely comfortable and supportive. Dash lighting isn't to my liking (orange lights). Ride is very smooth. Acceleration is amazing. It is definitley faster than the SLS, and my wifes I35. Two drawbacks that I found. As mentioned before, the orange dash lighting. Also, the transmission seems to be on a turbo lag set-up. You mash the throttle, while already moving, and it takes up tp a full second to respond. This may be due to the traction control, I am not sure. But, once the tranny kicks down, hold on. She really takes off. If they do not have the I finished by tomorrow night, I will take it out again, to do more "research". It is in no way the fastest car on the road, but very fast indeed. If I was in the market for a new sedan, The G35 would be a contender.
