My first response was incorrect. Sorry.
>The five main interior colors for each year are listed below, meaning that some of the lower production colors such as turquoise are not shown.
Because the sampling of the database isn't uniform.
I'm sorry to keep pressing the issue but I'm just not understanding the problem. I'm a computer programmer for a living and I've architected my share of databases so I'm trying to understand why a turqoise interior would not be listed as an option within your table that stores information from decoded trim tags...perhaps I'm just not informed enough about the way interiors were coded on the trim tags? The interior portions of my trim tag decode as follows:
67-12637 = Custom Interior Coupe
779 = Custom Turquoise Bucket Seats
3S = (Z23) Interior Decor group
Is 3S (Z23) the deluxe interior package and therefore why the color is not listed? On the otherhand, since I have 779 listed, couldn't one assume that custom turqoise bucket seats means that the rest of the car's interior is probably turqoise in color as well?
