At that price I'd guess there's something wrong with it. It's been smoked in, mileage is insane, or it's been up north and it's rusted to hell underneath.
At least that was my experience as I went through my recent t4R search.
This helps tremendously with getting a good deal, if the guy cant spell its harder to find the ad, if an ad is hard to find, others wont find it easily. My black 4runner was listed as a "4 runner" and it had terrible pictures and it said it had a bad clutch and a CEL so it scared any remaining buyers away.
