Hi, Kyle,
The best place to see and compare Cobras and talk with the owners/builders is at Spring Fling. Now that The Fling is "ON" again, my advice is to plan a road trip to London, Ohio for the third week in June. The days to see the most will be Friday and Saturday. Check around the hotels on Saturday morning and bum a ride in the parade. Most any Cobra owner who's there by himself will be happy for you to ride along and if there was any doubt in your mind whether you wanted a Cobra, a ride in the parade, amidst 100,000 or so thundering horsepower will make you a believer.
In the meantime, check
www.cobracountry.com for a list of manufacturers and contact the ones which look interesting for their sales brochures. On Cobracountry, you'll also find Curt Scott's "Guide to Cobra Replicas" (not sure of the exact title), which is a great source of information and well worth the twenty bucks or so. Depending on your level of interest, you may want to stop and visit a couple of the manufacturers and check out their operations on your trip. Also on Cobracountry is a list of classified ads for Cobras. Checking this list periodically will give you some idea of what's popular, how other guys have built their cars, what's available for how many dollars, etc.
As stated above, there's a vast wealth of information here on CC; use "search CC" to look for comparisons, answer specific questions, etc.
As with anything else, there's so much more to "Cobras" than meets the eye of the uninitiated, and the sky's the limit. Some guys build very nice Cobras for $20K or less; some spend many (MANY!!) times that.
