The Ferrari-Maserati dealership inside the Wynn Las Vegas casino and hotel, which charged visitors $10 each just to look at the cars, closed last week after 10 years in operation. The dealership, a joint venture between Penske Automotive Group and Wynn Las Vegas, is being sold and will reopen at a new location once the deal is finalized, said Anthony Pordon, Penske's executive vice president for investor relations and corporate development.
