I was looking for street and track performance when I bought my Cobra. After considering those who offered turn key cars, I decided on Superformance. My car has 14,000 + miles, best choice I could have made. I have enjoyed quite a few track days, never being trailered. Simply remove the top and side curtains from the trunk, adjust the tire pressure, put on a helmet and you are track ready. These cars are incredible as set up from the factory. At the end of the day, load back up the trunk, readjust the tire pressure and make the 90 mile trip back home. My best advice is to talk to owners who use their car as you anticipate using your car. Don't be shy about asking them to take you for a ride. A number of very nice Superformance cars are listed here.
