Brought in my 2009 Kia Optima, which had just turned 150,000 miles. Been hearing a noise under the hood for about a week, looked up auto repair shops in my neighborhood on Google, and quickly found that Sam's had a lot of 5-star reviews (and great feedback). I'd dropped off my car, and within an hour Sam himself had called me back, telling me the problem had been diagnosed (busted cap on a catalytic converter) and that they had also heard another noise under the hood. Upon investigation of that noise, they found the stock spark plus were still installed (because I'm a dummy and I'd never changed my spark plugs), so he scheduled a repair for the cap and a tuneup. By 1 PM the next day, my car was done. Funny how a couple simple fixes can make your car run like it hasn't in years. Sam was very polite and gave me suggestions about how often spark plugs need changed so this doesn't happen again. Thanks a lot, Sam Auto Repair and Collision!
