Maven, General Motors’ mobility brand, has expanded its offerings to include a new monthly service, Maven Reserve. Maven members pay a monthly fee to reserve a GM vehicle for 28 days.

Members can download the Maven app to view pricing by market. Maven Reserve allows members to select from a range of pricing options including hourly to daily or monthly, according to GM.

Initially, the Maven Reserve vehicles include the Chevrolet Tahoe and the electric Chevrolet Volt.

Maven Reserve is available now in Los Angeles and San Francisco with plans to expand to other cities. The service was developed initially for entertainment and entrepreneurial communities seeking on-demand transportation options and longer-term access to vehicles, according to GM.

The Maven Reserve experience includes a dedicated parking space for the duration of the reservation and a personalized walk-through of the vehicle. Insurance and $100 worth of gas are also included, and there are no membership or application fees.

“At Maven, we’ve matured our platform to meet the dynamic lifestyle needs of our members through multiple sharing solutions,” said Julia Steyn, vice president, General Motors Urban Mobility and Maven. “Maven Reserve is an innovative approach that answers requests from members for longer-term reservation options.”

Maven Reserve provides vehicles for the lifestyle needs of all members, including those who may be on short-term assignments, business trips, production shoots, and vacations, according to GM.

“Maven Reserve helps our members be there for the moments that matter most, both personally and professionally,” said Megan Stooke, chief marketing officer, General Motors Urban Mobility and Maven. “Carsharing is evolving, and Maven will continue to adapt to members’ wants and needs.”

Since launching in October 2016, Maven City carsharing in Los Angeles has experienced an average monthly member growth of 56%. Maven City in San Francisco has grown on average by 31% monthly since launching in September 2016.
