A new first-of-its-kind subscription service from Cadillac USA will allow members to switch between Cadillac vehicles at will, rather than own a single vehicle.

With the new “BOOK by Cadillac” program, offered by Cadillac in the USA, for a flat monthly fee of USD $1,500 customers can get access to popular Cadillac vehicles without the commitment of leasing, financing or buying.

Membership is month-to-month with no long-term commitment required, and members can switch between vehicles within a single week, or they can opt to keep an SUV for the entire winter (for example) and then switch to a sedan for the entire summer, if that’s their choice.

“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 chief marketing officer.

Maintenance, insurance and detailing of the vehicle are all handled by Cadillac, and members can use a mobile app to reserve vehicles that will be delivered to their specified locations via a white-glove concierge service.

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