While the cars value is a matter of opinion, I think this case proves the point of factory documentation and before any purchase researching the car. Talk to former owners, make an internet search, talk to other collectors. This is especially important if the car has been restored as fresh paint, new interiors, and "clean" engines can hide things. Also above all else take a qualified person along if you aren't..I understand the owner of this Yenko passed on having a noted collector look at the car to asscertain the condition and value.
