 This is my second G35X.  I loved the first (2004).  This car has been even better.  I am actually getting better mileage as well.  The original Goodyear tires were poor, but a step up from the previous car's horrible original tires.  I replaced them with Hankook tires after 29000 miles. No complaints there. I am still on my original brake pads after 41000 miles.  I can't believe it, but I have them checked, and they are fine.  It might be due to my use of the autostick . This car is a lease, but I will likely purchase it at the end of the lease.  I drove the 2009 with the 7 speed auto and 328 horsepower.  There was no real difference. The Bose premium "studio on wheels" sounds great.
