update on #3 4runner. i went to look at the 4runner & the frame looked much better in person than the pics posted, that area i was concerned with was just the factory coating flaking off with surface rust on the bare metal, no pitting or scaling at all, frame was still thick & intact everywhere beside surface rust on all the welds & other parts like the rear diff etc. & the rims had numerous big spots of the paint flaked off & heavy pitting/corrosion in those spots, never seen that on 4th gen sport rims, thought they were a polished aluminum & clear coated.
if it was just based on the frame & interior i would have bought it.. but, after inspecting the frame & a quick overview of the body & interior i popped the hood to check the normal things, had a brand new mobil 1 oil filter & at first looked like clean new oil... i noticed the coolant overflow jug had nice red coolant in it but it was down about 1", checked the dip stick & cap & saw some signs of milky oil, that was enough to make me pass for now.
not worth asking the owner what it was & getting the "oh i never noticed that" excuse. he was a asian guy that didnt speak english & had his friend interpreting, he said the oil was just changed & never had any problems. it may have been the low coolant was from it getting sucked into the engine from a bad head gasket or cracked head etc. either way, i didnt want to take a chance & buy it.
