The appointment was scheduled a few hours earlier due to cancellation of prior appointment . The device advisor told me that Micheal didn't perform diognostics for my check engine light which he did and was told he could just advise me on what to do. In order to get him to do that I scheduled a oil change. When Micheal arrived he first said that I would have to schedule a separate appointment for the diagnostic . The had trouble with internet speed and wanted to use my wifi which I agreed to but had problems with him wanting my password . After performing a 15 min diagnostic his advise was to replace the part that I had installed for over 100 dolllars myself then paying YM 70 dollars fora 15 min inspection. After conversing for a few minutes Micheal came accross as knolegable but reviews had no years on nearly all of the great referral .
