Duster was totalled
Glad to hear you were both ok, that is the most important thing.
This is my BIGGEST fear when driving my old cars. I got rear ended once by a guy doing 55 and he admitted he didn't even touch his brake pedal. He shoved me into the car in front of me and so on, ended up being a 5 car accident.
Don't write the car off yet though, especially if it is sentimental to you. Anything can be fixed if you put your mind to it, it's easy to just get another body but it's true love when you fix what no one else would.
