Rambler was a separate, compact car line within Nash. That car was discontinued after the 1955 model year although it would revived. This Rambler is a different car and larger car altogether. This became the Rambler Classic and Rebel in 1958 when American Motors became the primary name instead of a sub-brand stiocked by Nash & Hudson dealers.
I love the wild multi-color patterns on these late Fifties Ramblers, particularly the wagons. And take notice of the four door hardtop wagon in the photos.
