2006 Chevrolet Corvette 2dr Convertible (6.0L 8cyl 6M)
This car is absolutely worth every penny. The steering is much better than the 2005 model, and the power is exhilerating. The interior does seem a bit cheap but it is still comfortable. Surprisingly the highway mileage is actually pretty good, assuming that you do not hot dog around.
I like the steering the best. Strange as it seems, the handling of the '05 model reminded me of a truck. Chevrolet compensated for this in the 06 model by placing a smaller steering wheel (among other things under the hood) to improve this.
None at this time. It is the ultimate car in my estimation
