I bought an '06 Coupe, blue/tan, 3LT, nav, magnetic suspension, dual roof, paddle shift. I've put about 500 miles on it, and it is a fantastic car. A few minor faults - small rattle here & there, cowl shakes a little with the roof off, etc. No major problems at all. Nav system is terrific. Mag shocks are great. Paddle shift is a little tough - the Italians do a much better job at it. For the money, it is the best "super" car out there. Don't buy a Z06 - adds $20k, way too bouncy, noisy, & hot. Porsche? I've owned them - a lot more money & only marginally better on build quality. Italians? Same thing. Save your money & get a Vette.
Power - 400 hp is enough for this car. Nav system is excellent
More attention to build quality. Just because this is a "bargain" supercar doesn't mean it should feel like one.
