Rare beast.  GM's foray into pillarless hardtop stations wagons was beautiful but brief, only lasting for the 1957-58 model years.  AMC started the body style in 1956 and other makers did a little more with it - with Mercury even adding a 2-door hardtop station wagon, but by 1964 the bodystyle was gone (with Chrysler being the last holdout).

I think the GMs (Olds/Buick) had the nicest styling of them all, but they were all pretty cool to me.

This is a nice one, though the custom touches don't really hit a home run with me.  The 455 is a nice addition, though.

Oooo... plastic grocery bags.  We haven't had those here in a few years!
