Hello my name is Josh I have been working as a mechanic for ten years. The average shop price in Portland is 200 to 300 dollars an hour, I offer on site diagnostics for 50 dollars and then a hundred an hour for repairs after that . Oil change are a flat fifty dollars after you buy the necessary products . Tire patches are a flat fifty. Breaks are a flat 75 for one side of the vehicle so either front or back . 150 for both . Thank you for your time and consideration and I hope this finds the people who need an honest mechanic but can’t afford an arm and a leg that the shops are going to charge.
