I was in the same boat as you David. I bought my kit without ever driving a Cobra. You can tell just by looking at one and hearing it that you know it's going to be fun to drive.
I've driven a few Cobras since then though. Garrett (justbetter) very kindly threw me the keys to his Blown LS1 Superformance the other week. Trust me you wont be dissapointed by how they drive. Awesome, simply Awesome.
Cheers
