Just spent almost $ 200.00 to have my black car detailed, including clay and compounding. It came back to me wth a multitude of swirl marks and more surface scratches than Madonna's face. There is absolutely NO way that the light scratches would not come out if compounded correctly. The door sills were water spotted, the hood and trunk edges were not touched and were caked with polish dust. Nothing was cleaned or wiped down under the hood. The interior was average. When I pointed out the numerous issues to the detailer, his response was "I got what I paid for" - which was a glorified wax job. Lesson learned!
I cannot recommend this detail shop. Your best bet is to bite the bullet and go to a Penske Auto Dealership and have it fully detailed by professionals who know what they are doing.
