I had a problem with the muffler and i took my car first in the morning. The mechanics were not there yet so i needed to leave my car. They called me 3hrs later telling me i need to change my converter in order to fix my muffler and gave me an estimate of 2k. I am pretty sure they were trying to take advantage of female customer who seems to be not knowledgeable in car system. I wouldn't go to this shop anymore.
