COMPLETE RIP OFF!
My husband brought in our car for a detail and had a $50 coupon. He left the car with them and they said that he could pay afterwards. He told them up front that he had this coupon.
When he came back, they insisted that he didn't qualify for the coupon because they didn't do a "full service" and charged him $199.99 plus tax for the detail. For a flippin' detail! I didn't find out until after the fact when I looked on our credit card statement. I don't know why he paid it, but I would have put up a HUGE fit. That is such a rip off. They totally scammed him into paying the money because he was in a rush to get the car and leave.
WOULD NOT RECOMMEND.
