Hey guys I'm new here..

okay so i feel like a dumbass already about this.
but i was backing up like enough so i could get the lawn mower out of my garage.. well my door caught on the wheel of the other car in the driveway and I didn't see it because I was looking backward and I kept backing up to catch a glimpse of the door being hyperextended backwards...

The door still works. Like the hinge's and everything work fine but the door will not shut now because there's a metal peice rubbing and stopping the door from shutting..
The pictures below should help explain what i'm saying a little better...

Car is a
1989 Mercedes 300 SE

I need to know the best way to go about fixing this because being a college student, I really dont have the money to have the car fixed..

My idea...
Take Door off
If need be. take door Panel apart.
Beat metal back into place slowly with rubber mallet..

Things I need help with..
How to remove the door..
If Need be How to remove door panel
Electrical stuff and diagrams.
