Decoding GM 17 Digit Vins and RPO Code List

I came across this while researching some info. on an older vehicle, figured it would be useful for folks here. You can decode all 17 digit GM VINs and there's a tab (which I haven't researched yet) for decoding vintage VINs as well. The RPO code list is all 188 pages of GM RPO codes, don't make the mistake of printing it like I almost did!

Note that these are only active RPO codes, GM reuses common codes (the JBx brake codes and LSx engine codes for example).
