Dub. To my knowledge there were only 5 made, so unless you know the right people or happen upon one in a museum, all we see now are replica cars. I say "all" we see but these replicas are extremely gorgeous cars and I would love to own one. That being said, the replica values vary. I have seen them for as little as $ 25,000.00, all the way up to $ 150,000.00.
If by chance one of the originals came up on the sales block, I have no idea what the going price would be but the insured value is said to be upwards of 5 million.
I'm sure some of the guys have more insight and info on this. NW-99SS (Nathan) from Cold Lake has one and probably can write a history book on them.
