After a bad state inspection experience at a different service station last year, I decided to try Shirlington Shell and am so glad I did. The staff was friendly, professional, and kept me in the loop as they did the inspection and required repairs. They even removed the sticky, expired DC parking permit from my windshield, and my car smelled great when I picked it up. They followed up with a thank-you note and phone call to make sure I was satisfied with their service. Thank you, Ron and staff!
