Nick, When the frame for your car, vin# 1852, started its run down the frame line a pair of doors would have started down the door trim line. Like wise at some point the engine destined for vin # 1852 would begin its trip down the motor line, being dressed for installation in the frame for vin # 1852. There would have to have been a marriage point where the dressed frame with it's engine and body installed met up with the doors. Your car is a fairly early vin # so maybe some of the assembly process wasn't quite up to speed and maybe the door came from a pre-built supply of doors or perhaps there was a problem with one of your doors somewhere between the factory and the Quality Assurance center that required a different door to be installed. Actually the DeLorean assembly process was quite simple to schedule because they were all alike. When you have many options and colors, getting the right fender, door, seat, wheel, tire, engine and so on to meet the right chassis at the marriage point is a bit more complicated than was the case with the DeLorean.
