They were quick, polite, and efficient !! They plugged her tire and sent her on her way in 20 minutes. I met my daughter there as I wanted to make sure she was OK. Turns out the owner, Mark, was there. He put my daughter and her friend at ease, acting pretty much like a father would! Can't say enough about this place! Great owner and super employees!”- Joanne G., Marlborough, CT
