For all you Metro, Firefly, Cobalt, G5, etc. owners, here is a site that will
tell you what the build date of your car is, plus it lists all the options you
have and tells you how rare your car is. Just enter your VIN:
Comprehensive GM VIN Decoder
The website can be kind of confusing at first (It makes you think it hasn't done anything when it has...just need to scroll down).
Using this site and Autotrader.com to get VINs, I was able to make a table of the number of Trailblazer SSs that were built each year like below. I know no one here cares about that particular table, but thought its example might spur someone to make a similar one for, say, Geo/Chevy Metros.
Code:
