Mascot, that looks super clean, and it has the rear locker. It's priced too high though. It's probably worth about $3,500. Look at the alternator. Look for oil leaking down onto it from the valve covers above. Give the tie rods a good wiggle, see if their worn. If so, use these to talk the price down. They are comon issues, and pretty minor. Look at the condition of the spare. Find out if the tools and plug in light are still present in the back cargo area. Listen to all the speakers (dry rot in the paper cones is common). Ask about the timing belt and spark plugs. Put it into 4Low and drive around. If it wasn't used much, it may have difficulties engaging (lights on dash will still blink instead of turning solid). Easy issue, just sludge buildup. Also, it's common for a few of the dash light bulbs to be out, such as gear indicators.
That rig looks great. Just get the price down
