So how similar are the clamshell wagons from GM?


I'm assuming they were all based on the same platform from 71 to 76 with different rear quarters, rear and grille treatments?


I know the olds custom cruiser obviously and I've seen the same looking wagon in Chevrolet impala.


Was there a Buick and/or Pontiac wagon based on same platform?

 

Yup 71-76 Buick Electra Estate and Pontiac Grand Safari are all clamshells on same platform.
When I was looking for a clamshell I checked and researched for a long time which one to buy.
I found the Custom Cruiser best to my liking, and when I found this one, the math was easy

 

thanks for the info fullsizelover
I think out of all of them the impala is the cleanest looking wagon. olds is a close second
