This service was to correct a concerning vibration that recently appeared with our 2006 Toyota Avalon returning home from a 600 mile trip and was most noticeable when driving 60-70 mph. I called on a Saturday and Cavalier scheduled an appointment the following Monday. After about 1 1/2 hours, while I waited, they re-balanced the tires and corrected the front end misalignment. The car again drives smooth and vibration free. Let me add that the mechanic worked into his lunch hour to finish the job. I really appreciated that effort and thoughtfulness.
