WOW!!! Many more pics in the listing https://orangecounty.craigslist.org/cto/d/deland-pontiac-firebird-custom-kit-car/6790854882.html
It looks better than this one that's still for sale. https://columbus.craigslist.org/cto/d/columbus-very-rare-vw-split-bumper/6785252537.html
Looking at it I would have guessed it was based off a 71-73 Mustang, not a 3rd generation Firebird. I like it, but not enough to pay anything near the asking price. But I do Like it.
"Also this car is sold together with molds that it was build from. With this package you would be able to remanufacture any part of this car if so needed or start our own manufacturing." The molds alone should be worth quite a bit for anyone who wanted to start a small business building these.
The Aussie Fords was the first thing I thought of, but as for the mopar part ( front end) Hint of 70's big Mustangs?, Shelby?, Javelin a bit/maybe?, but face on view made me think of new generation Challenger. Yet now after you mention, it does have that Charger look....And Mustang...and.... But I have to admit, I was kinda shocked it's a Fire Chicken under a different skin. Only pet peeves I have, GT on the grill, SS on the dash, and a F-Bird on the steering wheel I've never been a fan of radical kit cars as IMO they seem to always look like a full scale version on a kids "customized" model kit. Oddly this one made me look again a few times. Fire Chicken or not donor, it hit me as a "?" Ford in it's looks... I'd put a 351 Cleveland in it, keep the GT on the grill and loose all visual GM relationship I even like the painted turbines, and I hate painted turbines!
