ATLANTA — Mercedes-Benz USA’s online portal now allows franchised Mercedes dealers and independents to source and buy Mercedes-Benz inventory and is now integrating vehicles from Sixt Rent-a-Car, the world’s premiere affordable luxury car rental service, the company announced. The site, MBonDemand.com, is powered by RMS Automotive, a Cox Automotive brand.

MBUSA sells a majority of its off-lease inventory digitally through MBonDemand and has sold over 200,000 vehicles through the site in the last four years. Expanding on its stated goal of being the “one-stop shop” for all Mercedes-Benz wholesale inventory, MBUSA is integrating third-party sellers’ Mercedes-Benz inventory into its wholesale inventory platform.

Sixt is the first partner to be integrated into MBonDemand with its off-rental inventory in the U.S. now being available in search results. Represented in more than 100 countries worldwide, the Sixt vehicle fleet is known for its high proportion of premium cars.

“Our goal is to be the online destination to source Mercedes-Benz wholesale inventory,” said Al Katz, general manager of pre-owned, remarketing, and fleet operations for Mercedes-Benz USA. “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.”

The addition represents the first Mercedes-Benz inventory listed on MBonDemand that is not located at an auction site. Whether buying directly from MBUSA or third-party sellers, vehicles purchased from MBonDemand are backed by the “Best or Nothing” brand promise, executives said, and all inventory is subjected to a rigorous condition report process to provide dealers peace of mind on their digital purchases.
