I recently used a Groupon certificate for car detailing by A-Z Auto Center in Brighton. The result was terrible?little better than a simple wash and wax with interior shampoo. The wheels had dirt still packed in the crevices and dirty film on all areas except the outer surface. The interiors and exteriors of the windshield and rear window were streaky. The wax finish had swirl marks in it, and the paint finish had many small scratches that were not taken care of. The roof still had tree sap stains on it. Although the door jambs and sills were cleaned, the seals on the trunk lid and hood had not been cleaned of debris and dirt. The headlights were filmy and finely scratched. The floor mats were still wet and stashed in the trunk along with some maps that had been soaked. And the radio was tuned to a station different than the one it is usually on, and volume was very loud. Based on this experience, I would not recommend the A-Z Auto Center for anything, and certainly not for auto detailing.
