Yeah, I can jack up my very well used/high mileage car and the doors open and shut exactly the same and the gaps do not change whatsoever. One of these years I need to actually rebuild the hinges so it's right and fix the solidly welded striker but this car is in the 260-270k mile range as far as I know. Someone DD'd it until the year 2000 from new in NE Florida.
