Speculators eye flipping the rare 911 Sport Classic, made in limited numbers.

Porsche leases ban 911 S/T lease transfers and resale for at least 12 months.

Lessees pay excess mileage fees making high miles less profitable for flippers.

By leasing, 911 S/T costs much less upfront than six-figure purchase price.

Leased 911 S/T depreciates faster, reducing profit potential for speculators.

Porsche wants to discourage flipping and ensure loyal owners enjoy the 911 S/T.

Huge demand and interest stimulated speculation on the collectible models.
