I've had my '66 since 1974 wen I purchased it from a GM exec. @ the Tonawanda engine plant. I'm trying to determine the rarity of the car based on build stats. options, color & production #s, but Chevrolet doesn't list how many coupes were built w/900 paint codes, only that there were only 1190 total units sold, Can anyone help me out??
