My parents were in a rut with six cylinder, three-speed, middle grade Chevrolets -- 1937, 1938, 1941, 1948, 1950, 1954 and 1959. I remember the 1941 and 1948 as the 1941 was sold to a family in the next block and the 1948 went to my Mother's foster brother who lived next door and drove it until I was in High School. Finally for 1965 my Father got a new Impala with a 283 four-barrel with dual exhausts.
