It's hard to say. A lot depends on the body condition the rear valence looks rusty. The rear seat area looks nicely painted, but looks to me like they just painted over the rust. You need to see the floor pans, frame rails, under the fenders, under doors, etc. and around the gas tank in the trunk. The interior seems rough. Engine looks ok, but how many miles since last rebuild? From the pics I'd say its a little high, unless its something real rare and special. Also how much you got to put in it? If its a long term deal maybe it's ok, but if looking for a DD, then you might be taking a big chance. Go drive it and completely inspect it.
