This is my 2nd 4 runner. I have only replaced the water pump and timing belt. The truck still looks great inside and out. If you want reliability Toyota trucks are the way to go. I expect to get at least another 150k. I don't drive like you mamma either, these are hard miles. The 4 wheel drive is there when you need it, it will climb some steep hills. If you are worried about good dealer service- don't, you will not need it!
