Mark,
Your posts are getting a little dry. I will assume that I and others may be taking them wrong... Your comparison of a 67 0-1 IPC to a taxi Cab is a little insulting - don't you think?
As Who thinks of them? Some 427 COPO Guys years ago may have looked down on a Yenko 350 Nova... and some of the other COPO's... If it was built a COPO - then it was a COPO.
Your comment above pertaining to COPO's:
"Quite possibly these cars may have been ordered using the COPO process, but until that is proven I doubt anyone will consider them COPO's as we commonly think of them"
As who thinks of them?? Either they were built COPO by Chevrolet or not...
Please keep an open mind here....
Phil
