Quality Tune-Up Shops hasn't wronged me yet, in the maybe over 2 years I've been taking several of our vehicles there. Always prompt service and the price isn't too bad. The only reason for the 3* is that according to my wife, they're a little sexist. Last time she took her car in for example, they'd play that you're a female and you're fodder routine. Then she has to call me on the phone and I'd explain what we need done on the vehicle, and the price will quickly drop 1/3 less.
