late to thread. you folks are all over this one...no such thing as a factory Vista-Cruiser coupe (all four doors, but 2 seat or 3 seat versions), hence the unusual B/C pillar look on this one.
I learned something with this one..the Vista-Cruiser was Cutlass-based (Buick had a similar A-body wagon too though, right?). Also, I always thought the big one...like the 98 sized car..was a Vista Cruiser but found out it was a "Custom Cruiser"
