I have an example that shows why some of us don't trust a dealership. My cousin has an 03 4Runner and the dealer wants $75 to install a new cabin air filter. It costs less than $20 at their parts counter. To install it you open the glove box, remove one phillips screw, remove the old filter and slide in the new one. Oh, I forgot you have to open and close the passenger side door, too. If they charge about $50 for five minutes labor, imagine what they charge for other simple operations. Another 4Runner owner was charged extra for a five tire rotation, was assured that they checked all the tire pressures and that the spare was good to go, in the rotation. The problem. The spare was at home in his garage, and the front tire with a ding in the rim was still on the same front left location after the rotation. It's things like this that make people shy about trusting dealers. It was not an error that hurt the vehicle, at least not this time.
