Thirty-nine years of honest diagnostics in Oak Lawn. ASE master techs, six bays, and a service advisor who will tell you what the car actually needs, not what you can be upsold on.

Mike O’Malley opened O’Malley’s Auto Repair on 95th Street in Oak Lawn in 1987, with one lift and two bays. Sean, his son, grew up under that lift. Sean earned his ASE master certification in 2010, took over the shop in 2014 when Mike retired, and expanded to six bays in 2019.
Same lift is still in Bay 1 today, still on its original hydraulics. Mike checks in on it about once a month.
Today the shop runs six bays, three ASE-certified techs including Sean, a service advisor up front, and a loaner car for any job over three hours. We work on anything road-legal, foreign or domestic, gas or hybrid.
We do not upsell. The car needs what the car needs, and if you drove in for an oil change and your tires are still good, we are not going to tell you to replace them.
Whatever your car is doing, the person on the lift has seen it before, the part is either on the shelf or a same-day order, and the number on the invoice is the number we told you on the phone.
"Check engine light came on Sunday. Sean pulled the code Monday morning, told me it was a $28 gas cap and not the $800 sensor the dealer quoted, and we were on the road by lunch. This is why we drive past two chain shops to get to O’Malley’s."
"Sean was up front. He said the brake pads had life left, the rotors did not, and he would rather do the rotors now and the pads in six months than upsell me today. Who does that. Saved me $200 and I will be back in six months."
"Dead battery on a Monday morning. I called at 7:30, they had a loaner at 8, my car was tested and swapped in under an hour, and the loaner went back when I picked mine up. Twenty dollars less than the dealer wanted for the battery alone."
