These are very limited, 1776 made or less, can't remember exact numbers. Some of the earlier ones were less and the numbers are different for 1:64 and 1:18 scales. The RAW Camaro was the first and brings the biggest dollar value. Check Ebay and use the word RAW in your search.
They do not consider these chase cars. That series is sold only as Raw with no painted version in that release. Yea, that Camaro is one of the Hot ones to get. The 67 Nova just came out and 57 Chevy not to long ago.
