Robert was friendly. He communicated well and explained everything he was going to do with my car. He is good as well. I think it's easy with a mechanic, because that's his job and he does it every day. But he did it quickly. I was very satisfied with his service. Thank you!

A++ Highly recommended! Bryce was very professional, knowledgeable and punctual. He explained to me in detail exactly what he did and showed me the parts he replaced. I will definitely be booking Bryce for my next appointment.



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.



Very impressed with the quality of work. Ned was on time and on budget. There were no surprise extra costs. Ned even helped me out with my other car, even though I didn't have an appointment for the other car. He took care of all of my car problems and he even found me a coupon for an oil change. I will be using this service again.

How can we help?
