Yeah, this is definitely not a finished list. The truck VINs are missing the '14 Sierra/Silverado and SUVs as a whole.
Plus I had downloaded the '13MY to decode the VIN for our new Terrain and that list was on its 6th revision.
Edit: Now that I'm looking through it, it's also missing the Regal, LaCrosse, Corvette, and SS.
