I got my Explorer from a Quality Auto and they thought they were going to beat me, that I was just a dumb college kid. It was making a funny sound and everyone thought it was the tranny. I paid 1000 down and was willing to take the risk. Turns out it was only the ball joints. I love the car it has a smooth ride, and AC after 16 years. I'm happy and wouldn't trade it.
Power everything, AC, smooth ride.
Underneath is very rusty and lots of people complain about the same thing.
