Mercedes has a luxury car subscription service, too

You can subscribe to tiers the company hasn't disclosed at prices it hasn't revealed.

Last month, car brands fell over themselves announcing new luxury vehicle subscription services. Latest but not least, Mercedes has added its own part-rental, part-concierge service to the list. A pilot program will begin in Nashville and Philadelphia this June.

Compared to services announced by other brands, we don't know much about Mercedes-Benz Collection, as the company is calling it. Subscribers will be able to choose between several tiers, though it's unclear how they differ. They'll be able to choose from a 'broad array' of the automaker's vehicles, including the high-performance Mercedes-AMG models. Like with other services, customers will be able to swap between vehicles on a whim.

Mercedes-Benz neglected to mention how much its service will cost, though competing ones cost between $600 (for a Volvo) to $2,000-per-month for BMW and Porsche. Like its higher-end rivals, the Mercedes-Benz Collection lets customers engage concierge services through a dedicated mobile app to, for example, arrange for staff to deliver a new vehicle to the subscriber's location. The monthly fee also covers insurance, 24/7 roadside assistance and maintenance costs.
