The Boxster is one of the models included in the new Porsche Passport subscription program. In November 2017, Porsche will roll out a subscription-based mobile app called Porsche Passport. In addition to exchanging vehicles frequently using the month-to-month program, users don't have to worry about the extra miles they put in while showing off their new wheels. While Porsche is hoping to tap into user trends and plans to discontinue the test subscription program if it hurts sales, it isn't the only luxury brand taking the leap. In 2017, Cadillac also launched a subscription service for residents in the New York metropolitan area — that app-based service costs $1,500 a month.
