I own a 2001 4Runner. I'm leaving for a 900 mile trip across country in a week, and my 4Runner is at 60K...the dealer wants to do about $400 worth of "preventive maintenance" (replace tranny fluid, clean and adjust brakes, replace coolant, inspect fuel lines, spark plugs). However, I have a local mechanic who can do it for cheap. Do you agree with this? Do you think anything else needs to be done? My question is the timing belt...should I have it changed or not? The vehicle is running just fine.
