If I could give zero stars I would. I left my car there all day and all they did was use ALL my gas. They charged me $140 for a "diagnosis." They told me what I needed from the "diagnosis" and it was to get A fuel induction and Fuel injector services which would cost me around $900. I'm sorry but I'm not a moron and you could have told me I needed those before the $140 and before using all my gas. I found another shop which I used for years before I moved to central phoenix that will do the needed work for less than $300. The shop I used in Scottsdale also does an inspection for free because they care about their customers. This place is a joke and such a scam! Do not go there!
******* UPDATE *******
The owner called me and tried to "fix" how things had gone down. The worst part is the second I said I wouldn't change the review his mood and demeanor changed completely. He was rude and said he was glad to never have me in his shop again and hung up. If he treated me with respect through the entire phone call, I would not adding this little update.
Treat everyone the way you want to be treated, even people you do not plan on doing business with.
