My sister took her car there where she was charged $200 for a diagnosis she had already obtained at a local AutoZone; of which she informed them from the beginning.
The $200 was based on manual labor and a smoke test to find a leak, non of which she understood or needed since the reason she went there was to change a failing part. For people who don't understand auto mechanics, I do not recommend this establishment due to the precedent. My own opinion is that she was taken advantage of because of her lack of knowledge.
Edit (03-15-2017): updated my review to illustrate a more accurate depiction of what occurred.
