 Buy a Toyota 4Runner with total confidence.  This 4R has been totally awesome.  I have not had one single unscheduled repair.  I have changed the oil and replaced the battery and tires as needed.  In May of 2015 I replaced the timing belt, water pump, struts, brakes, rotors and spark plugs. I have the big V-8, but get a consistent 22.0 mpg city/highway.  This car is roomy, comfortable and is an outstanding travel car.  I cannot think of one single negative thing to say about this 2006 4R-SR5.  Every day I see tons of these models on the road, in spite of this car being 12 years old.  No one want to get rid of this model, and why should they?  I salute Toyota for a job well done on this one.
