Check out this never-built Roadmaster Limited Wagon 3rd-row seat option, with Limited seat, cut-down side panels with padded arm-rest areas and cupholders! Very cool! Buick should have made this an option!
If you blow up the LAST photo - with the lower gate closed and the glass open, you will see a quarter panel emblem that says 'Park Avenue'. I'm guessing this was going to be a car show concept vehicle, not necessarily meant for production.
Cool! Where oh where did you find this? Looks like you were snooping through some classified documents there. I don't want this roadmaster thing to get you in trouble Texas mike. We are all worried about you and want you to just come back home
Mike posted these on a Facebook group as well, and the original GM photographer showed up and made a comment. (I don't think he even remembered taking the pics until he saw them again....) Didn't have anything to add about the wagon though, unfortunately.
