Video of the aftermath posted on social media showed a damaged SUV backing into the building, followed by an employee rushing out. The vehicle pivoted in a lobby area and drove out of the opposite end of the building.
CarMax said the driver was a customer whose vehicle had been appraised. He was later arrested.
“We appreciate the authorities’ swift response to this terrible event,” the company said.
The Associated Press left messages for the Inglewood Police Department on Saturday evening.
The incident was initially reported as an active shooter situation, but Torres said that turned out not to be the case.
Inglewood is a city located about 10 miles (16 kilometers) southwest of downtown Los Angeles.
