Dang! That's kinda cool. Looks like only 7,332 Blazers were built for the '91 model year. This as compared to just shy of 19K Blazers built for '90. I bet you're damn close to having the youngest Blazer out there, and I bet you have the youngest one on CK5! Maybe someone will post up on if VIN information indicates the numer in the series that yours was built. I don't know about that.
