the engine which may have low miles. I own and still drive a 2006 Highlander. It has been well maintained runs great 225,000 miles but sooner or later the starter, alternator, computer, lights, struts, fans, AC, seats, and countless other parts going to start going like the organs on a 90 year old person. When your monthly repairs bills are more than the payment on a 5 to 10 year old vehicle it is time. I have already planned the funeral service this summer or maybe a retirement party and very light use.
