MBonDemand.com, the online private store from Mercedes-Benz USA, now includes cars from a third party.

U.S. off-rental Mercedes-Benz vehicles from Sixt Rent-a-Car are available on the site, a portal powered by RMS Automotive.

The luxury car rental service is the first partner to have its Mercedes inventory integrated on the MBonDemand platform.

These cars will also be the first vehicles listed on the site that are not at an auction site.

Al Katz, the general manager of pre-owned, remarketing and fleet operations, at Mercedes-Benz USA, said in a news release: “Our goal is to be the online destination to source Mercedes-Benz wholesale inventory.

“With the recent addition of Sixt Mercedes-Benz inventory to MBonDemand.com, dealers can enjoy a greater variety of vehicles to choose from, while maintaining confidence in their digital purchases.”

Mercedes-Benz USA sells most of its off-lease cars digitally through this channel, according to details shared in a news release. It has moved more than 200,000 units through MBonDemand in the past four years. 

“Mercedes-Benz has an aggressive digital-first strategy that RMS Automotive is well-suited to support,” said Nick Peluso, the president of the Manheim Digital Marketplace and RMS Automotive. 

“We are committed to helping progressive clients like Mercedes-Benz USA respond to market transitions with digital solutions that turn inventory faster while driving dealer success.”
