Finding certain cars
I looked for nearly three years for a 1966 Coronet 440 with a 383 and A/C.
Color did not matter.
Along the way I discovered they only made about 1665 of them (and that's not factoring the A/C)!
By contrast, 5,000 383 Coronet 500s were made and a whopping 18,000+ 318 Coronet 440s were made.
I don't think colors are broken down by number, but I've seen percentages.
