I love wagons. 1956 Plymouth Belvedere. in Model Cars Posted July 19 Wow! I love it! Brings back memories……. My parents actually had two, brand new, 1956 Plymouth wagons, a lower trim level though- Savoy or something like that. Both 6 cylinders and 3 on the tree. The reason they had two was the first, light green colored, one didn’t make it thru the first year- total lemon. The second in quite ugly gray wasn’t much better. I remember the dashboard ashtray was quite crude and sounded like fingernails on a blackboard when you pulled it open. This was quite a disappointment from the excellent quality our 1954 Plymouth had, so it was back to Chevrolet for them after that.
