Update : Jeremy the manager called and offered to do the remaining repairs for free. I appreciate their effort to correct this. Thanks Sun Devil.
*While I appreciate the quick and friendly service I always get from Sun Devil, my last experience was not so good. I brought my car in because I had a check engine light going on and off and the car was running rough. I was told new spark plugs and a fuel system treatment would fix it. I paid the $650 for the repair and went on my way. The next day my engine light came on and the same problem persisted. I brought it back in and they explained that now I needed oxygen sensors and that it would be another $700. I do not know if my car needed the prior repairs but something is wrong and maybe they didn't diagnose it correctly.
