James was very kind and professional, he was even able to show up early to assess the situation. I did not feel like he tried to up-sell or "get one over on me". I would definitely use James again!

David was knowledgeable, professional and thorough. I will have David do all my future car repairs.



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.



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