Engine repair service near Savage, MD

Had been going to this guy for 15 years. In April 2014 Took my car in, guy kept if first 2 weeks, didn't address the problem. Afterwards I had to return the vehicle 6 times and he still didn't repair the problem. Took the car to the dealer who found the problem and said GAC had installed a cheap aftermarket part (not OEM) that was incompatible with the vehicle that doesn't take aftermarket parts. This guy ripped me off and refuses to reimburse me. Also I asked from the beginning for the parts he replaced, he lied saying I never asked for the parts. He did the same thing to my daughter. I would never take my car back to this guy after the way he ripped me off.

We know your car inside and out!

Very disrespectful owner who is a "Know it All" type of guy. Would let me talk and hear what I'm saying but did not listen to anything at all. I was explaining my situation. told the man I have went to different shops, got estimates and told him what all four shops said and from my experience on cars this is the issue. He says "I'm not going to give no stupid estimate on anything over the phone. I said sir, just a rough estimate. He of course acted stubborn so I'm trying to give him money so I tried again this time saying, well, how about just putting a new engine in my car. He still said He's not giving a estimate in a disrespectful manner. I politely took my business away from him. His workers are very respectable but THE OWNER IS A Complete DOUCHE
