I have a Toyota Sequoia that has almost 100,000 miles on it. It is in good condition and all maintainance has been done to date. The dealership has recommended that it was time to get the timing belt replaced. $450. Also everytime I bring it in for an oil change and tire rotation they recommend to have an allignment. I noticed that this recommendaiton was given to everyone there wnen I was there. Necessary? They said there was slight feathering. I did not notice any problems in driving. DMR
