We have a special thing for the obscure factory show cars of the Motor City, and few are more obscure than the 1966 Rambler St. Moritz station wagon.

Unveiled at the Chicago Auto Show in February of 1966, the Rambler St. Moritz is sort of an odd fit in the design timeline at American Motors. Nothing like the advanced and exciting Project IV vehicles rolled out a bit later in June of that year by AMC design chief Richard Teague, the St. Moritz was based on a production Rambler Classic Cross Country station wagon, but with a twist. The gimmick, if you will, was a custom greenhouse with a pair of curved observation windows for the rear seat passengers.

Named after the famed ski resort town in the Swiss Alps, of course, the St. Moritz was constructed around a winter sports theme with a ski rack on top and and a snowflake motif for the interior. There were three rows of seats, with the rearmost seats facing the rear (known in the car biz as “Dramamine seating”) and upholstery in dark blue Dupont Corfam, a simulated leather product of days gone by. Snowflakes embroidered in metallic thread completed the winter sports theme inside, while the exterior paint was a snowy ice-blue/white in candy pearl. The roof area between the two large glass panels was trimmed out in stainless steel.

We don’t know this, but we’re guessing that the massive side glass was constructed in acrylic plastic—Plexiglass or suchlike. On a one-off show car with little production intent and a shelf life of one season at best, real glass would have been a fiendishly expensive undertaking. (As a side note, the production Classic wagon for ’66 used contrasting two-tone paint that approximated the look of the St. Moritz greenhouse.) Except for a press release and a handful of photos, little seems to remain of the Rambler St. Moritz, and we assume the wagon was scrapped long ago.
