Your timing to become "afflicted" with the cobra bug is excellent. In the spring there is a huge "kit car" show in Carlisle, Pa., and virtually all of the builders are represented. ERA normally has several cars there, as does Unique, Superformance, Backdraft, Factory Five and others. If you have some spare weekend time (and some frequent flyer miles) it would be interesting / fun / wise to visit places like ERA (New Britain, Ct) and if an aluminum bodied Kirkham is in your budget - that would be a cool shop to visit. I'm not sure what your intent is (kit, partially built, turnkey) but with ERA for example, you can order any level of "finish" from 100% assemble it yourself to a full turnkey. Same with Unique. There are shops that will assemble cars for you as well and people like Levy Racing who sells turnkey FFR roadsters and Coupes. There are also a lot of outstanding used cars available that represent excellent value as a lot of "cobraphiles" are closet collectors and don't drive their cars very much. I almost bought a 7 year old "used" ERA FIA car that had only like 700 miles on it - but the seller decided not to sell, and was ordering a second car (a GT40) to park along side of it. I know of one ERA 427 SC for sale right now in the low $40's and there are quite a few Superformance cobras available - check out
www.cobracountry.com to get an idea of what is out there, with which options, for how much $$$$$. You will see aluminum bodied CSX cars for $125K and good quality glass bodied cars of all makes from the $30's to the $60's. Researching cobras is fun!!!!! Enjoy.
