Jason, you hit the nail right on the head! On a level driveway, the front door, fully open, measures 28 1/2 at the "belt line" strip (i.e., the only place on the door that could have dinged you). Good call. I would have guessed the door opened more or less level, but it doesn’t. I think you have your culprit (the dealer) but you knew that anyway. Now you have to prove it. Good luck.
