The hours says 6pm but I was turned away at 510 pm and all I wanted was an oil change. There was no one in line. It didn't seem busy. There was a mechanic shooting breeze in drive up area. Too bad I really liked this place had gotten good service in past but will not go back. Almost rude when they told me that they didn't take cars after 5. Change your hours .
