I have noticed the same dents in every DeLorean car door that I have looked for them including both the passenger and driver's doors. These dents on every car are located approximately in the center of the door just below the molding. On some cars it is much more noticeable than others, but I have noticed them on perhaps more than a half dozen cars so far. The dents protrude outwards and appear to be coming from the tubes of the window regulators hitting the inside of the door as they over-torque at the end of their travel. My car is no exception. I have rather noticeable dents on both doors. I am suspicious that it is the OEM window regulator that is at fault and not the heavy duty replacements sold by the vendors. My driver's door still has the OEM window regulator, and the passenger door regulator was already replaced before I got the car. Since I have owned the car for over a year now, the dents in the drivers door has gotten worse! Yet the passenger door does not appear any worse. The driver's side window gets more use (since I actually do use it for a toll booth window and to have security gates scan a bar code which I refuse to stick on my car. I don't recommend throwing change through that little window, though. The last time I tried it, both quarters missed the basket. I had to get out to fetch them. The funny thing though, I was so close to the basket that my door wouldn't clear it. I couldn't pull much forward since the gate was closed, and I had trouble backing up since the guy behind me was already up my a... But I did make out like a bandit once I got out and started picking up quarters that everyone else lost.) Okay I get side tracked too easily.... So I suggest to everyone who wants to keep their pristine doors dent free to not use the OEM window regulators anymore. Or if you do, be very careful to not run the windows all the way up or all the way down without taking your finger off the button immediately. I hear that the OEM regulators do not stop automatically, and this is partially the cause of why they tend to prematurely self-destruct. Before anyone accepts this as the gospel truth, lets have some input from the other DML'ers. I have yet to take my driver's door apart, but by peeping in through the front door light it looks like I have an OEM window regulator in there. DMC Joe showed me how to pull the light out and look inside, and he said that it looks like an original. My passenger door definitely already has the heavy duty regulator, but it went bad shortly after I bought the car. It filled up with water because no one removed the drain plug when they installed it. (Read more about this in the archives.) Walt Tampa, FL
