Shady car dealers in my area will take pictures like that to throw you off. I see rust, a deformed ac line, aftermarket headlights. Theres also some sort of leak on the manifold.Can't see the pictures too well, taken at night and odd angles. Miles are high @ 170K even if owned by old man, babied and highway miles mostly.
Most will probably tell you that $4,500 is too high. Run a CarFax on it if you can get the VIN to see how many owners to start investigating any BS.
