Trusted by thousands of happy car owners



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.



Patrick was very professional and polite. He inspected my car and found that it wasn't as bad as I thought it was. He is very friendly and I would DEFINATELY recommend Patrick to all my family, friends and co-workers.



I can't say enough about how pleased I am that I found YourMechanic and Raul. I'm from out of town and didn't know who to contact to fix a truck I was borrowing. I searched the web and found YourMechanic.....thank goodness. I found Raul to be professional, an outstanding mechanic and the price was more than fair.

How can we help?

Our service team is available 7 days a week, Monday - Friday from 6 AM to 5 PM PST, Saturday - Sunday 7 AM - 4 PM PST.
