 I've had my G35 for exactly a year now.  It has been an absolute blast to drive (straight line it might not be the fastest, but cornering and grip with some summer tires on it and its second to none).  Unfortunately, I've put almost 20000 miles on it and the way gas is going that part has not been fun.  If Premium ever hits 4.00 in NJ i think i'll be forced to trade it in seeing as that I'm only getting about 20- 21 MPG lately.  But if you want a great ride and to push your car to the limits, this is the car you want
