Is it Kevin or Eli??
You ask some interesting questions that are difficult to answer. If you feel you paid approx. $8k too much, are you asking if $30k or $22k is a fair price? If you have sentimental reasons for the purchase, then the final price paid is not as relevant.
I know of many COPO projects that have been sold within the last few years, but they usually do so via word-of-mouth.
Bottom line, if you want a COPO car, you have just bought a nice solid project, in a rare color, without common options (D80), that will look awesome if you restore it correctly, and hey, it might just turn out to be a bargain a few years from now
