just added one I currently own and a few I used to own... a couple of thoughts to consider...
under paint choice - for silver metallic you have 925 as the code, a lot of later 72 and 73 cars had code 936, but it isn't an option.
maybe add a spot for options from the factory - e.g. LSD, sport seats, factory AC, fuchs, etc, so real interesting data analysis could be done on % of cars with x, y, z variables could be determined.
on the build date - it forces a day, when many of the later cars only have month and year known...
cheers
