If I could give a NO star rating, I most definitely would.  I purchased the Groupon because who can't pass up such a great deal?!  Unfortunately, you get your money's worth.  Let me tell you about my experience: \n\nI went to Auto Tech, understanding that there might be an increase of price from the Groupon because my car uses half-synthetic oil.  After asking what the price difference was, the rude man behind the counter said $50.00 PER OIL CHANGE.  So on top of the amount that I already paid for the Groupon, they were going to charge an ADDITIONAL $50.00 per oil change.  Meanwhile, other businesses in town charge less than $50.00 for the complete half-synthetic oil change.  I politely asked the man if I went to Walmart to get the oil, if they would change it at no cost at which he said they would - they would just use the Groupon.   He told me what oil to get, and i went to Walmart to get it.  When I returned, he told me that I got the WRONG oil, and that I would have to change it.  I was already in a bind for time, and I told him I would run right back to Walmart and exchange it for yet another kind that he told me.  It was 4:00 then, and he said that he would not be open by the time I get back because he closed at 4:30.  First of all, Walmart is 5 minutes from this location.  Secondly, what happened to customer service? \n\nThe man behind the counter had HORRIBLE costumer service, and I would not recommend this place to anybody.  DO NOT BUY THE GROUPON!  I got a complete refund for all 5 vehicles I bought the Groupon for, and I would never step foot in this business again.
