Clean looking motor, look at the inside of the oil filler cap and the dipstick for signs of head gasket failure, if there is a mayo looking sludge stuff there, could be a sign. Also have a look at the water container, should be a clear pinky colour.
Always worth going for a test drive to see how it goes, mate, or if any one on here is nearby, maybe they could take it out with you.
Always go in low with the price, and let them come back.
