A man and a woman were arrested in the case, suspected of using the car that authorities described as "something out of a 007 movie."
The Irvine Police Department on Wednesday released a video clip that shows how the license-plate flipper on the white 2003 Mercedes C300 operates -- at the push of a button.
"Having it be sophisticated in that way, I've never seen that," police Sgt. Karie Davies told ABC7. "The license-plate flipping device, that's a new one. In 19 years I've never seen that used in this way."
According to a statement, police were investigating multiple cases in which a vehicle without a license plate was driven into parking structures to commit crimes. Before the Mercedes was found, it was unclear whether the plate was missing or concealed.

On Tuesday, an Irvine resident spotted the suspicious vehicle and contacted police. Along with the license-plate gadgetry, officers discovered "an elaborate gas-siphoning device that transferred fuel directly into the vehicle's gas tank," a news release said.
The Mercedes also contained burglary tools, evidence of identity theft, and stolen property, police said. During the investigation, detectives recovered a car that had been stolen from Irvine.
Yasmine Kambour, 37, and Chris Huynh, 44, both of Garden Grove, were arrested and booked on suspicion of vehicle burglary, vehicle theft, identity theft, possession of stolen property, and possession of burglary tools, authorities said.
