I smell fish on this one.

-look at the rear wheel arches, there are white plugs in the holes. Someone has stripped the flares off this one. If it never had flares, it wouldn't have the holes.
-cheap ass quick struts in the front
-aftermarket rad hoses, screw clamps, rad cap too (I think), battery terminals I bet not much OEM has gone back into this one.
-rust and/or damage on passenger fender bottom in front of the door
-new backing plates on a rusty rear axle, hummm...
-there is quite a bit of rust on the axle back portion of the chassis, rusty trailer hitch looks to have been recently removed.

I don't think this one is a gem despite the desirable options. I wouldn't buy sight unseen.

Edit: almost missed the pre-dented roof and the roof rack rails removed and no strips put back on. Hope they put the screws back in the holes. This shouldn't be a high dollar 4runner but likely will be.
