Here's a postcard the original owner used to hand out to promote his Esso station back in the early 70's with the Copo sitting at the pumps. Looks like it had black wheels on it here, and hard to see from this image but it appears to be without the rear spoiler at this time. Neat little piece the current owner got from the original owner when they met to discuss the car years ago.
