5 /5 Anthony Cerro: We needed some work done before our car could pass inspection. My now former mechanic misdiagnosed a bad thermostat for a blown water-pump, and quoted me over $3800 for that and the rest of the repairs. We called McKinneys for a ballpark estimate, and it came out just a little over HALF of the other guys figure. Once they got to take a look under the hood, they found and fixed the "thermostat mistake" the other guy made, and by that afternoon, my new brakes and ball-joints were installed and good to go. My car drives like new, and I will definitely be giving this shop all of my future business!
