Not trying to rain on anybody's parade, as great as the car looks, it is a bit more difficult (okay, a LOT) to sell a race car than an original 'Cuda for the price range you're seeking. Honestly, everybody wants them the way they left the factory. Oh, and it has a roll cage? That hurts the value, actually. A rollcage can be undone, however if done correctly (i.e. cleanly). Several nice Ebodies didn't sell or meet their relatively low reserve prices reserve on eBay becuase they had been altered.
You didn't say if it was originally a 'Cuda, or a Barracuda? Any buyer would want to see the VIN to see what car you started out with. The value of the mods you put in it is inconsequential if they divert from factory originality. You're getting 15, maybe 20% to the dollar you spend on aftermarket mods when you elect to resell.
Realistically, $15-20k if it started out as a Barracuda, $25-30k if a 383 'cuda, $35-40k *MAYBE* if it was a U or V-code in a previous life.
All in all, a very nice looking car nonetheless that would be a great showcar! :thumbs:
