I brought my car in for a touch of paint. Only to find out later that they had replaced my license plate frames (both front and back) to their own "Auto Quest" brand. I did NOT purchase my car from them at all! How presumptuous they are to replace my license frames without my permission nor telling me beforehand!!
I will never return to this place for any services in the future. What they had done to me is totally gross!!
