Factory Five if you want bang for the buck. Excellent frame and geometry, low cost while still being nice. Kirkham if you want the very best money no object. The finest engineering you can get in a cobra. Superformance if you want everything basically done when you get it to just pop in an drivetrain and go. In the middle of the pack. FFR's and Superformances are fiberglass and will not dent. Lots of places to fix glass body damage that just happens when you drive the car in the real world. Aluminum, 1/4 of the weight of Fiberglass, cool factor
, but you have to search out your repair options. +/- to everything. But the most important thing is to just GET A COBRA!
