For a flat monthly fee residents in the New York Metropolitan Area will have access to all the Cadillacs they want, when they want.

BOOK by Cadillac is a first-of-its-kind automotive subscription service; for $1,500 a month members will gain entry to whichever Cadillac their hearts desire without the commitment of financing, leasing or buying. Vehicles include current year Platinum trim Caddys like the XT5, CT6, Escalade and V Series.

Using a smart phone application members will be able to request the latest top shelf Cadillac models on-demand which will be dropped off at the members' doorstep or specific location by a white-glove wearing concierge. There is no limit on mileage or duration; meaning you could opt for a ATS-V Coupe all year round, yet swap into an XT5 every other weekend when it's your turn to take the children.

“BOOK by Cadillacis an innovative new option targeted at a growing class of luxury drivers searching for access to various cars over time, dependent on their individual needs, coupled with a hassle-free white-glove exchange,” said Uwe Ellinghaus, Cadillac chief marketing officer.

Cadillac claims BOOK frees members from the "baggage" of traditional vehicle ownership, the monthly nut covers registration, taxes, insurance and maintenance costs. Membership is month-to-month with no long-term commitment expected.
