You know it's a reliable location when the staff themselves will tell you not to buy one of their items because they know it doesn't work. That I respect very much. Means that they're genuine.
I like O'Reillys in Millwood. The guys in there can be very helpful and everything is easy to find. If you need something specific and they don't have it they will get it within one to three days. They also have very reasonable prices.
Helped me with my License plate, helped me find the right screws and helped me install it onto my car! Super nice people and very good pricing
