The birth date on Marcia's temporary license, August 5, 1956, is Maureen McCormick's actual birth date.
The car in which Marcia learns to drive, takes her driving exams, and competes with Greg in the obstacle course challenge, is a 1974 Chevrolet Caprice Classic convertible.
Marcia's temporary driver's license lists her date of birth as August 5, 1956, her age as 17, her weight as 95 pounds, her height as 5'3" and her eyes as blue. The date of issue is January 15, 1974.
Herb Vigran, who played the driving instructor, also played the clerk at the trading stamp redemption center in the first season episode 54-40 and Fight (1970).
The actual location of the "don't break the egg" drivers test between Greg and Marcia is on the Paramount lot inside the Van Ness gate, where a parking garage is located now.
