Andy,
I'm not familiar with that model, but based on age, as long as it wasn't abused, It should be a fine saw...like they say, they don't make them like they used to. I've got a mid 90's JET, and although happy with it, I'm not sure weather or not I'd recomend a new one.
Check out the cutting capacity. 16 inch wheels should give plenty on 'throat', but make sure there is at least 8 inches of depth of cut (the measurement from the table to the highest the guard can be raised.
Will the owner let you run the motor? Check out the bearing and tire condition as well. Fire away with more specific questions.
