Well a real Yenko car would sell in excess of $150K+
If someone builds a respectable clone, with all the right parts, aluminum block, date coded parts, etc. it would probably be worth about $75K to someone wanting a Yenko but doesnt have the big money needed to buy a real one. You could have the car you want, a lot cheaper than a real one and still be able to drive and enjoy the car.
I have seen some gorgeous clones built better than the originals but I have also seen some major junk that is not worth a 1/3rd the price that is being asked.
I am assuming that this is the car you are talking about?

Not what I thought you were talking about by your original post, looks like a really nice built drag car to me with a ton of money invested.
