I would happily and with great confidence recommend Mark. But as a service, I"m not sure. My first experience was not great. I had to have a warranty appt due to the first mechanic's faulty work. I had issues w/ my car after the first mechanic completed work. Mark- second mechanic had to correct errors and provided a thourough explanation of my vehicles performance. I would book Mark again for all and any service.

Tom went above and beyond to make me as satisfied as I could be. His communication was excellent. Friendly and professional and best if all, my car is running great and he did it without unnecessary repairs. I would and will highly recommend Tom and Your Mechanic to everyone. Thanks, Rob Miller.



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.
