This may be an explaination for that. In a auto salvage yard teh wheels are usually removed and teh cars arent sitting properly on their suspension, they are unibody and the way they sit the bodies flex. Over time that may lead to door closing issues,that and the hinges and door strikers are worn out LOL! But I assure you when a Mopar is repaired properly the doors close like any other car. The fit and finish on the other makes was definitely different though.
