Well, the S/S is greatly speed limited and has smaller brakes. My point on collectability was concerning the Demon. The problem with the S/S is it is basically an unlimited production Demon without a trans brake, so it'll forever be, "Oh, that's just an S/S, not a Demon" in the eyes of the collector market. Then, you have the Redeye, and, for all intensive purposes, is every bit as capable as the S/S outside of the drag strip and comes at a much cheaper price (as of right now, no rebates or power dollars avail on the S/S).
This again is why the car will just not see mass appeal.
If they're still making them in 2 years, I plan to order one myself. It will be a trailered track car for me.
