The word "wholesale" on the sign could tell part of the story. Maybe it's a car left over from a brokered deal that went bad. Or perhaps it's a BMW demo with a negative history. Many cars used in the BMW Drive Experiences are disqualified from CPO or OOP; they are passed over by the authorized BMW dealers and consequently end up in the Manheim auctions. Definitely pull a Carfax and ask for vehicle disclosures.
