My grandfather would take us kids for a ride in that car doing 80MPH airborne over small hills.
The one in the front kinda looks like my old Dodge Dart slant 6 beach mobile I had early 80's in Hawaii.
Looks to be a Buick though, close.
I guess you mean originally, some of my Grandfathers drove some pretty advanced cars.
I remember growing up my Grandfather had something like this that was my great grandfathers similar to this, but was an older truck with wooden wheel spokes even, and it looked like a gypsy wagon on the back end of it.
Too young at the time to remember it right, I think it might have been an old converted REO Speedwagon.
