My husband went here for a smog check. Prior to that, he had gone to another smog station that charged him $90, with the end result of his truck not passing. That technician could not offer any advice on passing a future test. Evidently, that was not his job. My husband immediately went to 5-Star, explained the situation, and the service consultant checked the sensors and told him there would not be a problem passing the test, which there was not. Very friendly, understanding and informative folks there at 5-Star! We will utilize them for all our vehicles in the future. We give them FIVE STARS!
