This one looks to be just OK for the price lower end model Hi-Ten bike with cheap 27 inch wheels and components. It looks to be in good original condition but will need a complete overhaul with new consumables cables, brake pads, tires and bartape, 30+ year old OEM tires and grip on bar foam aren't much of a selling point, so figure on spending another $100-150 on servicing the bike. I think in the the $200-300 range you should be able to find something nicer that's basically ready to ride.

This one is a much nicer touring model with a chro-mo frame triple front and cantis for $180.
