We did the interior detail. Gene did an amazing job! Ensured he was able to keep the car a bit longer just to make sure the cloth seats had time to dry, and he could assure he got the stains out. He did them multiple times for no extra charges. Paid extra attention to details. Thanks... Wife was very happy with this "birthday present".

I spoke to more than a half dozen companies. Supreme Detailz rose to the top for quite a few reasons. Gene started by fully explaining the process, the products used, answering every question and concern I had. It's always difficult to leave such an investment in other people's hands. Gene put my mind at ease. It's very apparent at the results also.
