70 Yenko Camaros

[AutoInsane]

Ok this is probably a dumb question... why aren' there any 70 Yenko Camaro's?

[Warren Malkin]

Probably not enough demand, and insurance would have been expensive. Isn't that the reason behind the creation of the Yenko Deuce in 1970?
Byrne Bros. Chevrolet out of White Plains NY, had their "Yenco 427 S/C Super Cars Special Price Clearance Sale" going on in Feb. of '70, according to an ad placed in an issue of Super Street Cars. So they must have been stuck with some cars.
In that ad Yenko was misspelled.

Jack Douglass ,of the former Douglass Chevrolet in Hinsdale,Illinois reported having Yenko Camaros for sale well into the 1970 model year.

He remembers vehicle insurability as one of major factors to slowing down super car sales.
