It's "worth" whatever the market will bear...
Is your question really: "How much should we list it for in a potential sale?"
That one's easy, too- Always start high, and work down.
Lowering your price gradually, until you find your buyer, is always more satisfying than selling it immediately, and then wondering whether or not there might have been a higher price buyer out there.
it's always time, versus price: Sell it fast by selling it cheap, or take your time, market the car to the largest global audience possible, and wait for the deep-pockets to show up.
Have Curt list it for you on his CobraCountry website.
A nicely built and documented Contemporary Classic is a premium Cobra replica - With a side-oiler, they can bring 50, 60, even 70k...
The magnesium wheels are another premium item- If they are real, vintage magnesium Halibrands, they might be worth 5-10k all by themselves (based on the condition, and whether all 4 roll true, and balance easily)
And a full custom aluminum body? That's a mega-huge premium factor, too.
It
could be a 6-figure car,
if you find a 6-figure buyer for it.
Naturally- other associated used-car factors will also apply: how many miles are on it? How well documented are those miles? Receipts? Service logs? Photo history? - all that stuff matters.
