As always, they go out of their way to resolve the issue(s) that concern your vehicle. Such was the case with my almost 19 year old car. After test after test it was concluded it needed a new catalytic converter. Due to the high replacement cost and some other needed repairs in the near future, I decided not to repair and used the car as a trade-in on a new vehicle. I thank them for working so diligently on the above. - Les P.
