Yeah but the
new "Eleanor" cars have all been signed and authorized by Carroll Shelby himself... now if the seller could produce some similar documentation from Don Yenko...

Besides, Shelby Mustangs (even clones) have always commanded more money than Camaros.
Let's face it, the reason everyone is questioning this car is because a super clean big block Camaro (minus matching motor) is worth what... $30-35K? Tops? So if the Yenko Can-Am motor is worth say $20-25K, how the heck does that add up $125K plus?
I would much rather have the Yellow "ZL-1" Camaro Charley sold last year. At least it was unique.
