Anyone have any suggestions on how to deal with this? Short of getting a new car of course.

You should look at rust repair products by this company www.eastwood.com They have quite a few products that can help. For the outside you still cant go wrong with factory metal grafted in. On the inside the head liner material will cover it, but you should treat the rust with the eastwood products. They have very good service and support (they also have a forum for people using their products.
