The detailer cancelled an hour before the appointment. The finish had new swirl marks that were not there before.

Had my GMC Sierra detailed in my own driveway in Chicago. Tires and trim were dressed perfectly — not greasy at all.

My Toyota Tacoma had not been properly cleaned in two years. The paint looks great. The interior vents were slightly overlooked.
