Why drive a 640hp CTS-V in a city with a 25mph speed limit? Why dream about escape when you can just book to an Escalade? Why drive one Cadillac when you can drive five?

Those were the questions behind Book by Cadillac, a first-of-its-kind luxury subscription for those who value experience over possession. Subscriptions granted access to an entire collection of Cadillacs through a single monthly membership.

The model was quickly copied by competitors like Porsche, and while the category itself never fully took off, the thinking behind it still feels very on the money.
