Cadillac has introduced a luxury vehicle subscription service called BOOK. For a flat monthly fee, BOOK by Cadillac gives members access to Cadillac vehicles without the commitment of leasing, financing, or buying, according to the company.

“BOOK by Cadillac is 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’s chief marketing officer.

BOOK members will have app-enabled on-demand access to the latest trim Cadillac models. The vehicles will be delivered via white-glove concierge to members’ requested locations and exchanged at their leisure or as their needs change, according to Cadillac.

Members can take to the winding roads in a performance V Series and enjoy a winter ski trip in an Escalade in the same week. Alternatively, they can keep an SUV during the winter months and switch to a performance sedan during the summer, with each vehicle picked up and delivered to their doorstep, according to Cadillac.

Cadillac takes care of the maintenance, insurance and detailing of the vehicle.

BOOK by Cadillac will first launch in the New York metro area, with plans to debut in other markets.
