Had my car for over a week. Ended up cleaning the fuel injectors and putting in new spark plugs. Next mechanic (a friend of mine who works for Mercedes) I took it to informs me that the plugs they put in it weren't new. They put used spark plugs in my car and charged me for platinum plugs. The engine was losing compression due to the valves so cleaning the injectors did absolutely nothing. Was charged $700. Don't go to this place they will rip you off and try to take advantage of you. Not trust worthy and apparently incompetent.
