I drive a lot of miles. Wanted AWD, previous car was a BMW 540iA and an SUV in the winter. It was either the Infiniti or BMW 530ix THe G35 is fun to drive, great NAV and stereo, and at least feels as fast as the 2000 540. Only have 1K miles in 2 weeks time, but I got the same or better milage with the V8 in the 540. Lacks the refinement of the German car but is $20K less than the 530ix. IMO the 530ix lacked low range torque and was a pig off the line. I am very happy to pocket the $20K and drive the G35year round.
