My appreciation goes to FlowerHill Autobody of Roslyn NY , for the fantastic work that was done to my new S550. A new rear bumper cover , rear diffuser & rear valence was placed onto my 2017 GT Premium. All the chrome emblems were replaced with Shadow black emblems. My 2017 GT Premium was window tinted all around with 30% 3M window tint as well. They have now worked on all of my Mustangs since early 2010. Their work is exemplar. This is now the second delivery of my 2017 GT S550. It was worth the wait. Hyperion is now back in my stable.Current mileage is just over 300 miles.
