My experience at Shirlington Shell was a pleasant surprise. I went in for a safety inspection (walk in).Not only did they fit me in toward the end of the day. I also asked them to replace my air filter with the new one I had on the seat and I got a friendly smile saying "no problem". They were very pleasant and offered for me to wait or to call me when the car was done. Just yesterday I received a text from them thanking me for my patronage. I will definitely recommend them.
