Looks like a great buy to me. Any car that is complete and in somewhat "running" condition is worth $1000 in my book. And that looks to be a good choice for a first restoration project, mainly because it is not one of the "high profile" cars most try to go after like the Camaros, Chargers, Mustang FB, ect. I do see a little rust in the bottom corner of the passenger side door....but that shouldn't be too hard to fix....It's hard to tell from the pictures, but the 1/4's dont look too bad.
And to the "too many miles" comment...Never mind that, NO one cares about miles on a car 30+ year-old that they are about to "restore". Maybe if it were some rare optioned car that had "documented" low miles it would matter...Besides if it actually is 156000 miles that seems low to me.
