Vince Geraci, who've I've corresponded with several times, was the AMC interior designer during this era. Also on the terrific AMC interior playlist at this time were the Oleg Cassini Matador option (the cloth upholstery always reminded me of Florence Knoll couches...and that's not a bad thing) and the Levi interiors.
The Sportabout was an extremely popular and handsome wagon when it was new. No one had anything like it. Of course, you have to be cognizant of style and an adult at the time.
