the only 1-door car I can think of is the BMW Isetta (and the other kindred microcars).

Its a 4 door sedan model

The Winchester family vehicle was constructed in 1967, and is the four-door sedan model. The four-door option is rare, for that usually was ordered with the station wagon. The four-door models were also used as cop cars, which is what the first Supernatural Impala was before being pulled off a studio backlot and repainted black. Standard models came with only two doors, which is likely why die-cast models of a 1967 Impala only have two doors.
