This car replaced my Infinity I-30, and while I have lost some of the luxury, I have gained in dependability, gas mileage, and I do like that remote start. I drive ~150 miles per day, 90% highway, and I average 35 MPG (the on-board computer shows 36.8, which is too high). Power (200HP+) is more than adequate, and hadling is exceptional for this kind of car. Currently over 70,000 miles, and no problems with the car at all. Very, very solid car - much better than any of the late GM cars I have driven. Will buy the '08, I think, when it comes out.
Power, simplicity, DIC, handling, gas mileage.
Stability program, AUX audio input, better leather.
