Justin was on time and thorough and explained everything. The wrong oil was ordered for my car through his service and parts department so he had to leave to go get the right oil for my vehicle and was very apologetic. Would definitely use your mechanic and Justin again for future service for my 2016 Land Rover LR4, super convenient and awesome price.

Joshua is an excellent person. Extremely professional and so very easy to communicate with. He did the work I asked him to do and also gave recommendations on other things that needed to be done. If we weren't moving to Gainesville Joshua would be the only one to work on our car. Seriously. "Your Mechanic" is fortunate to have this gentleman working for them. God bless, Josh and thank you. :)

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.



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.
