It turns heads, snaps your head back, and you can drive it in traffic all day and still have a smile on your face. It handles much better than the 2003 (I have one of those also) and the cockpit feels like a jet fighter. The trunk is larger, the transmission shifts wonderfully. It has no rattles at all, and when I brought it back for the free one-thousand mile checkup I had nothing to fix or adjust.
Power, handling, and quality.
The GPS system is horrible. Avoid it and get an aftermarket one. The CD changer takes up the entire glove compartment.
