Diagnostic services service near Laurel, MD

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

Garry the Manager is the BEST. I check sereral places for a price for a catalytic converter for my 2006 chyrler van. I got prices from $869.00 to $1100.00. I search the internet and found Monunment Street Auto. I called Garry and he quoted $473.00 for a catalytic converter. I could not believe what I was hearing. I left my work place and went to Monument Street Auto. Garry provided me with excellent Customer Service. An employee from the auto center drove me back to my place of work and he pick me up from work when the repair job was done.
