The crime, which was caught on camera, happened outside of a fitness club in Scarsdale on Friday. Two of the cars were later recovered in University Heights in the Bronx.
One of the thieves sped off in a stolen Porsche as a valet helplessly tried to chase after it. Two other thieves also made off with two Mercedes.
The valet then got into a SUV to go after the stolen cars, but eventually lost them on the Bronx River Parkway.
The search continues for the third car, and for the thieves.
