I went to this place because of the positive reviews, however I was blown away when I was charged $45 for 99 cent windshield wiper fluid!  
Although I do not doubt the knowledge of "Mitchell", he WILL take advantage if he can.  (And he took advantage of me.)  I asked him to just look at my car to see if it was driveable for a long trip.  I mentioned a few problems and asked him for suggestions--although he never really investigated anything.  He looked under my hood for ten minutes advised me to get a new muffler and then charged me $45...."to compensate for the windshield wiper fluid.....", he said.  This, he charged after glancing at my engine and telling me my 91 Infiniti was indeed drivable and without any serious problems!!!!!!!
I was never given an estimate beforehand, and I was very surprised to be charged anything (although a small fee is understandable).  However, he charged me $45 for doing nothing and diagnosing by having a "hunch".  Indeed, he could have set the price at anything and expected me to pay it, because he never quoted me a price beforehand.  I will not be returning to Mitchell's and advise others to stay away unless you have serious car problems.  He is not cheap and his business practices are questionable.
Thanks!
