Not knowing much about cars, I assumed I would be taken advantage of. Instead, everything that needed to be done to fix my AC was explained to me in full detail, prior to any work being done. The office personnel were friendly, courteous and knowledgeable. They gave me an estimated price and time of completion. The work was completed ahead of schedule, for a hundred dollars less than I was quoted. I paid them in full and asked for the keys to go get my car. Then they pointed out the door and my car was right there waiting on me. They walked me out to my car and when I opened the door, to my amazement, the interior and floor had been wiped down and vacuumed. I was very impressed and satisfied with their work ethic and professionalism and I will recommend Cien Motor Werks to all of my friends and you. Gratefully yours, JIMI K. Avondale, AZ.
