1967 Yenco Coversion

[Vette10R]

Sorry if I'm posting in the wrong area but I have some questions about a car I came across...

I found a 67 Yenko Camaro dealer conversion with very low miles for a pretty good price. Car has not been driven since 1978 hence the low milage and last time it ran was 1999 when it was started and moved to a different spot in the warehouse it is being stored.

I'm wondering how I can determine if this car is what it is and what it's actually worth in its current condition and what it's worth redone. She needs minimal work to get back on the road I.e. Fluids/gaskets/fuel system/brakes
/tires gone over to make road worthy. This car is straight as an arrow and shows very well, it's a true survivor and you can tell just by opening and closing the doors that it's a low milage car.

Now I'm told this is a dealer converted Yenko Camaro done in 1967 with permission from Don Yenko. Problem is I don't believe the seller can prove it due to records of the vehicle being burned down when the dealership burnt to the ground many years ago. The car doesn't have Yenko badging on it which I'm told the dealer converted cars did not get badging just the 427 and such..

So number one how can I tell if it's a real Yenko conversion without paper work. Number two what is she worth if a true Yenko converted car? I really like this car and want it in my stable but if she's not a true Yenko I don't want to pay the premium. Either way she's a beautiful 67 low milage 427 Camaro.

Any help is greatly appreciated! Thank you?
