David,
Don't take my comment the wrong way. I'm not making any remarks about the quality of a CSX car. I don't have much experience at all with them, so I don't know. All I'm saying is that to some, it's worth the extra $$$ to have a CSX.
If you want performance training, come autox'ing with me next year. Yes, it's low speed. But it'll give you a good chance to push the Cobra in a safe environment and learn what it'll do at the limits of adhesion. And it's a damn good thing you don't have a cupholder. You'll spill your drink on that fancy carpet.
