1978 Mercedes 450 SL convertible. Runs good but not restorable due to rust

This car lived on the Long Beach Peninsula in WA for 37 years and rust took its toll. I don’t believe the vehicle is restorable but it’s a lot of fun to drive. It has a hard top with a cracked rear window that attaches but doesn’t seal properly due to rust damage. It also has a soft top that needs to be re-covered. Out on I-5 a while back and it got up 100 MPH in a hurry. I’m sure it’ll go faster but I won’t risk it.Near new tires, ood brakes, ses no oil and no cooling system leaks. The power steering unit leaks a bit. I love to drive it in the summer and will miss it!!
