Antique diesel Mercedes 300 turbo

This car has an amazing turbo diesel engine very powerful and smooth clearly very taken care ofit's moving and driving could only drive it around small streets because it's not registered but I'm assuming it's running good and the highway as well The only damage is in the back as you see the post photos and it's got some rust around the seat bolts other than that everything works lights horn blower windows etc. Dashboard not burned bottom of the doors are not rusted
