Yep, past owner would of kept it. Ask me how I know... 69 Barracuda convertible... I know where the original owner in California lives but it's miles away from me... like on the other side of the world. No build sheet either so I can't get another tag made. If you have the dash VIN then you can decode some of it and going by the tags on other cars you can roughly guess when your car was made. As for original colour, try under the carpets or in the trunk.
