The slowest selling used cars are nearly all SUVs, though the Tesla Models S sedan tops the list.

The study from iSeeCars named the Tesla Model S as the slowest selling used car.

 “Many of the slowest-selling vehicles, including both Teslas, are older models in need of a redesign,” said iSeeCars Executive Analyst Karl Brauer. “But some, like the Ford Mustang Mach-E and Land Rover Range Rover, are new to the market, making it surprising to see them languishing on dealer lots.”

Used electric vehicles have more than doubled their days to sell even as prices dropped by 38.9 percent over the past year. The market shift away from electric vehicles can be attributed to several factors, including stabilized fuel prices, higher interest rates that make financing an EV more expensive than a similarly sized gasoline model, and ongoing concerns over charging options amid inadequate infrastructure.
