72 Dart 4 Door

I have not seen the car in person, and already have a nice 72 valiant that is being restored but we are short a car right now and I found this 72 4 door that seems to be in good shape, straight body, 225/6, automatic, 133k miles.

I kind of feel like the guy is overpriced on it so I was just wondering if anyone had any input on what this might be worth?
