Like mentioned above, the budget is what will set your goals. To make it a little easier,......there are 3 levels of cobra manufactures that I base on price, typically with quality, but NOT a rule. There are the lower end, middle and top end. I will not post who qualifies in this list, as I will be pounded upon but, if you email me I can give you my opinions.
Prices can range from $18,000 to about $40,000. Then you have the Shelby and the #1 cobra of all cobra's,.....The Kirkham, which can be had from say,
$60,000, and up over $100,000, depending on the up-grades and originality, engine ect. Building it yourself rather than jobbing it out, can save you a LOT of money,.... if you do it correctly.
Most everyone here on CC as a collective, can answer about any question you may have. Some are extremely knowledgeable in the history, others in building, body work (like me) engine's aftermarket parts ect. to help you build your dream cobra !
You can create a cobra cheap, or very expensive. I know of a local man that pieced together a cobra for $13,000. He lives on a gravel road (
) it's is green with berber carpet, an old 351 Cleveland (now a used 460) fairly ugly wheels, automatic with a 8.8 rear. He painted it in his garage with a old suction paint gun with dirt and fish eyes included. He'll bring it out to shows for a couple of hours for fun, then leave, which is great. But ya know what, he's happy with it and that's ALL that matters !
Take your time, study and listen, and build the car as YOU want.
You'll be in COBRA HEAVEN .
