I can’t say enough great things about this shop. Paul and Berj are both incredibly friendly and great at keeping you in the loop. They let you know the ballpark price and don’t BS you. After I was rear ended I initially went to the other party’s insurance company’s preferred shop and was told that my car was totaled. Brought the car to Superior and their quote was less than half for MORE work done than the original shop was going to perform. These guys literally saved me thousands and I’ll be bringing my car back here for everything.
