William was very friendly and very knowledgeable. He arrived very early for the appointment. Had all the parts necessary and finished ahead of schedule.

Stephen was very professional and spoke to me in terms that I understood. Although the news about the car was not great, he explained the why's and what it would take to fix it. I will call on him again. Many thanks!



Tim was great; offered advice instead of just blindly fixing. Also Tim was super friendly and very genuine. Highly recommend!



Yourmechanic.com is a woman's prayered answered. My stress was zero. I didn't have to drop off the car and wait for an outrageous quote from the corner mechanic. I was able to schedule and know the price immediately. I will use yourmechanic.com from now on. If you are in the Las Vegas area. I recommend requesting Scott Franklin. He goes above and beyond customer service.
