we where traveling from Southport to Niagara Falls, stopped on our way in Rockingham. My husband hear this noise and said it’s probably our brakes. We pulled into Dieffenbach dealer ship, and ask f they could help. They repaired the brake pads and roter system. Big shout out to the Service Manager that day, and the mechanics which did a super job getting us back on the road. Thank you for your excellent service. Now we where abel to meet our kids at Niagara Falls and we celebrated our 50 th anniversary. We will always recommend Dieffenbach Dealer to others. Super job done well.
