Q. What type of vehicles did the family drive?

Carol, on the other hand, drove only two vehicles: a 1970 Plymouth Satellite wagon, and a 1971 Plymouth Satellite wagon (which took the "bunch" on their infamous Grand Canyon trip). The vehicles were loaned to Paramount by the Chrysler Corporation for filming. Incidentally, the 1969 Plymouth Fury III convertible that "Mike Brady" drove was recently restored to showroom condition.

There were many episodes where Carol’s 1970 Plymouth was seen in the front of the house turning into the driveway, but the 1971 Plymouth Station Wagon appears in the back. It’s likely that all exterior shots of the house were filmed at the same time in 1969 for the first season, and not updated when the new car came into the show. Mike’s cars were never shown in front of the house.
