Easily the best car I've ever driven, and I've had a BMW 330I to compare it to. Excellent power from the rotary engine in any gear, at any speed, tons of torque, tight steering and stop on a dime brakes. This car looks like nothing else on the road, which is great. The Bose stereo is awesome. This car easily gives the most bang for the buck compared to anything else on the street, plus it has a usable back seat that the 350z and BMW don't. Gas mileage isn't great, but who cares? If you want great gas mileage, buy a hybrid. If you want to ENJOY your ride to work, or wherever, THIS is the car to get.
Speed, quickness, handling, styling, pretty much everything you want in a car. Lots of available options.
Better gas mileage, but not at the expense of power. Larger gas tank. Power seat would be nice. Maybe another inch or two of headroom. Analog mph gauge.
