I used to believe that all cars had the year of manufacture on them somewhere that was visible to anyone outside the car. I'd be with someone (always a guy) who would say something like.... "check out the '73 mustang". I thought the only way they could know what year the car was made was that it was "printed" somewhere on the back end of the car!
