It doesn't have the original engine, but he doesn't say what's in it now or why it was changed. Sounds like it was driven by a little old lady only back and forth to church on Sundays. Would like to know more about what options are in it and whether its always been an Arizona car. Would also like to see more than the one photo. But for only $1250, it doesn't have to answer to much. Looks like it could be a very good deal. He does give the street address of its location, which is unusual in a craigslist ad (or any ad).
My guess it had a diesel or a 267 in it. No one liked those engines. Probably a 305 or 350 by now. With luck maybe TBI injected but I'm not that lucky, nor that close to Arizona...
