Yeah I actually want this to be my last car for a long time so I can save up and some day buy a real nice newer 4runner. I'm not afraid to run one till 300,000 if it lasts me and is reliable. I guess I'm just scared of rust. Whatever they put on my roads in PA absolutely destroys cars. My family hasn't bought a used car that's lasted 200,000 before rusting out yet. I'm looking around down south (online) to see if I can find something rust free. Once I find something without rust I will have it undercoated this time. That being said, are there any particular rust issues with 4runners?
Also That is interesting you mentioned a tranny cooler. My friend just had her Neon do that exact thing and the car is junk now (not that it was a gem before lol).
They do rust, like any other car (except my BMW, which for some reason seems impervious to rust). There are some spots to check if you look at a 3rd gen. Many will have the bumpers rusting through. I don't really care about that because you can unbolt a bumper - its not the body. On the body or a 3rd gen, the rear wheel wells and the rocker panels are the normal problem spots. Mine developed a bubble on the rocker panel and its slowly coming through. I did nothing to address it, so its partially my fault.
I've looked a lot at dealing with rust (or more correctly - stopping its spread) with regard to my F350. I'm not a fan of undercoating, although some people say that the new formulations (used primarily in Canada) are much better than the old tarry or plasticy stuff.
So, I've started spraying the bottom of the ford with used oil, and will probably switch to Fluid Film come winter. yeah - I know, not exactly the most environmentally sound thing to do, but neither is building new cars.
The other spots to watch and keep clean is just inside the front doors where water runs down fromt he windshield. There's a spot that will clog full of debris. Also, inside the rear wheel well, just in front of the wheel, there's a spot where debris will pile up. Keep those spots clean.
