before this person came it took 4 phone calls, kept saying to call them back did not book appointment in advance when I wanted, then when I called after they said no problems they were less than accommodating. Who runs a business this way?! Prior to showing I was given a quote of $217.00 for a tune up?? 
This person Michael, was the most unprofessional person I have ever met, extremely rude, misdiagnosed the situation and refused to do the work and walked off as I was trying to find out what was going on. Waited 3 1/2s stayed 5 minutes, nothing but attitude.. BEWARE...would not recommend!!!! I called another company who is reputable, did a standard tune up and there were no issues as the rep Michael tried to assert.
