With three identical cars built at the same time and delivered to dealers 50 miles apart, it is entirely possible 2 or all 3 are involved.

Someone gave me Yenko ownership history circa 1990:

N578835 Cliff Ernst collection
N578842 Bob Trez, Gary Holub, Ed Cunneen
N578884 private owner, WI.

All three still exist.

In addition, I have a WI DMV record from 1983 showing N578842 was privately owned since 4/22/81 by an individual in Madison, WI.

Nothing changes the fact that Doug Martz asked me to look at a Yenko Camaro in Waukesha about 1981 and I did. I was not in the market. Cunneen later told me he bought it.

Between Dale, Yunker and Hult's Chevrolet, about 27 COPO Camaros were sold in this area. 12 remain in the wind. One of the Dale COPOs was found in 2015. No one had any idea what it was. Bet there are one or more still around here.
