Scheduled a full detail for my Porsche Macan and it came out flawless. Only reason it is not five stars is the appointment ran about 30 minutes late.

Average experience overall for the price. The seats were cleaned but the carpets were still damp when they left.

The work was decent but it took much longer than quoted. They did not bring enough water and had to leave early.

The ceramic coating they applied in Fontana has made washing so much easier. Tires and trim were dressed perfectly — not greasy at all.
