Mercedes-Benz 420SEL - Serpentine/Drive Belt - Ontario, California
Carlos came on time (unlike others who cancelled the appointment several times). He came, TWICE because of my car needed more parts than expected. Great job, friendly, very professional, I HIGHLY recommend him, and will make sure next time - if needed - he will be the one I ask for. Thank you Carlos
