My son's Lexus had a weird no start condition and electrical issues. Contacted Sim and he came out right away. Sim was great, and was able to quickly diagnose my issue.

Mobile Master Mechanic - Auto Repair Near Me

Considering buying a used car? Call Mobile Master Mechanic and have Sim do a pre-purchase inspection. He literally saved us THOUSANDS of dollars and kept us from driving away in a ticking time bomb lemon of a car. How do I know he's good, you might ask? When I showed Sim's inspection report to the salesperson at the dealership, he immediately left the desk and went into a 15 minute conference with his managers. When he came back I had two managers flat out call Sim a "liar", but I was able to refute every single one of the dealership's claims, and in fact showed that Sim had done an EXCELLENT job in finding major faults in the car that the dealership denied the car had. You know a dealership is shady when they will call a reputable mechanic's expertise into question when he has absolutely no stake in the game if you buy the car or not. Sim flat out told me to "RUN" from this car and we did! Thanks again! read more

Also extremely reasonable pricing, and got the job done quickly. I will definitely be referring friends to him, and will do business with him again in the future. read more

My car battery died and left me stranded on a Saturday. Was able to get it home, but now what?!

Roughly ten minutes later he was done, I paid the price quoted to me the day before, and my car started right up and has been running great ever since. I highly recommend this business, and I can be difficult to impress. This guy is the real deal and I will absolutely use him in the future. So lucky he is in town! read more
