I have been going to Sam for all my automotive service needs for 8 years now (2007 to present day 2015). The first time I stepped in his shop I told him I was fascinated with working on cars but had no idea where to start. He took a wrench and walked me through how to do an oil change, how to check all the fluids on my car, and what things to keep an eye out for that will wear-and-tear.
There have been times where I have called him where I was stuck at home with no idea how to fix the mess I created, and each time Sam has came through with a solution over the phone - I didn't even need to bring in the car.
I have had a Lexus (sold at 195k miles with no major issues), Mercedes (going strong with no major repairs @ 120k miles), and Acura (my precious baby currently @ 45k miles) - each of which have been taken care of by Sam
I know this is probably a perk for being a client of his for such a long time, but there have been plenty times where Sam has offered buying me lunch if I happen to come in during his lunch hour.
I have sent at least 8 friends to Sam for their automotive service needs (ranging from Mercedes, BMWs, Hondas, Lexus, Acuras, Toyotas) and each one have told me nothing but 5-star reviews - it feels great being able to give a good shop recommendation to friends so that dealerships aren't robbing them.
