Here is why, these guys are HONEST mechanics not interested in ripping people off. I know, you may find it hard to believe. Finding an honest mechanic is like finding an honest spouse or business partner, once you've got them, you never want to let them go! I was in there this afternoon after having troubles with one of my vehicles, certain that I needed at least a new starter and possibly more. Not the case, upon their diagnostic check they found there was an issue with a sensor, they reset it, re-diagnosed to be certain, tested it and everything was gravy. The best part was they didn't charge me a dime! Nothing, nada, zilch! Not even for the diagnosis which they initially quoted at $99.00 and I had agreed to pay. Even better than that, I was in and out in less than 30 minutes. If you haven't found your honest mechanic in this life, fret not, hope is alive, for now you have! These guys are the real deal and have gained a customer for life.

His own family members has warned me not to trust him and he scams people and I still went against What they said thinking that they were being vindictive. All reality I should have listened to the warnings. If you do any business with him at least you know now someone warned you.

I have felt taken advantage of many times using other auto repair places, but never at Aptitude Auto. They make the effort to explain exactly what is wrong and have shown me the bad parts to back up their work. This week I brought my car in because the brakes were squeaking. Juan told me what he could do to resolve the noise, but made sure I knew that I was safe without the repairs as well. It is rare to encounter such an honest mechanic- people who would rather be honest than just make some easy money. Thank you, Aptitude Auto!! You've got lifelong customers because of your fantastic service.
