Video shows the suspects throwing side mirrors they had broken off customer vehicles that were at the guard’s car. Then, one of the suspects threw a catalytic converter at his car and shattered the window.

The dealer’s service department director says that the thefts have been a continuing problem for the dealership. “This year alone we’ve been hit three, maybe four times, and last year, I want to say at least another four times,” he said to .

The service director says that it’s actually cheaper for the dealer to just pay out of pocket to get the converters replaced rather than go the insurance route.

The dealer is currently asking for help in identifying the thieves from the video.
