Quite possible answer : Someone got there door lock adjustment sheet and wrote the date on it .... then later when they were using that to adjust the locks they forgot it in your door. Or the flux capacitor malfunctionned and only your door travelled in time.... (okay someone day to do it with all the date references) -----Original Message----- <snip> >The paper I found in >the door has a pen marking in blue on the photocopy showing that they did the >door lock adjustment for my car on April 29, 1981, which doesn't make sense because the car wasn't built until June 1981. Could this be another DeLorean >Motor Company mystery to go along with the rest? Any ideas?
