Mark Winkler and the Porsche of Farmington Hills team are exceptionally professional and efficient. Mark is truly an expert on how Porsche models are configured, specifications, and how options function. Unlike many dealerships, Mark completed the trade-in evaluation and offer process within half an hour and had provided what I felt was a fair figure for trade. A test drive, review of available stock, and a deal agreed took another half hour. I appreciate a dealership that empowers their salespeople to extend a deal with no haggling necessary and no back and forth with management before a deal is agreed. The delivery process was also outstanding and similarly efficient. Bottom line: a dealership that treats their customers with dignity and respect.
