One other thing to consider is how you expect to use this car...if its going to be used primarily on the track, I'd seriously consider getting one with a cage (SPF R-model?), a fuel bladder would also be a consideration (the fuel tanks are, after all, between you and whoever is T-boning you on the track). If you intend to use it as only an occasional track toy, I wouldn't bother with either of these modifications. Just something to think about.

We have a new cage design that Olthoff Racing does for our cars that is not as intrusive as the "R" model cage but provides additional protection. The "R" cage is NOT recommended for the street due to potential unhelmeted head to cage contact. The new cage would be ideal for occasional track use as opposed to a dedicated vintage racer. The stock stainless fuel tanks will be fine for non competitive events, if going full tilt racing you are looking at $5000 for the ATL fuel cells.
