John is quite knowledgeable. I have been a loyal customer at Northside Auto for over 15 years now. John will not try to oversell you like the "quickiie "oil change/tune-up shops do. He does not use scare tactics to get you do do your repairs. I trust his judgement and will always value his opinions. Thank you Northside Auto for taking care of all of my family and friends. Yours Truly, Tim L. and family
