Especially after a minor car accident, you don’t want the driver’s side door to work any differently than it did before the collision. Maybe the window won’t go down and it scrapes against the dent. Maybe a body shop will just pull out the dent and repair the door. Regardless, anything less than perfect is unacceptable!
Hopefully, it’s not likely any suspension damage or alignment problems occurred since the damage was not hard. In minor collisions the police will not even show up at the scene, so whose fault it is will not factor into whether or not you need some repairs on your driver’s side door. It just is what it is as the old saying goes.
