All points I have wondered too Pete. I know the GMC line was originally created to give oldsmobile and pontiac dealers a truck line, but now that seems a moot point.
Buick is for sure curious, doesn't quite fit anywhere. Cadillac is supposed to compete with Lexus, BMW, and Mercedes, yet Buick also claims to compete against Lexus, BMW, and Mercedes, so in effect, Buick and Cadillac compete against each other. I always found Mercury to fit in a weird spot as well though.
Maybe in yesteryears the multiple car line ups had more differences between them, but now the lines seem awfully blurry.
