This went out over the newsgroups -- we've eliminated identifying information, but it's odd enough that it rings true and means the thieves have something new up their sleeves ...
Yesterday (Wednesday) my husband called Mercedes Benz road side service because my car (parked in the garage along with my husband's car) would not start. A technician from Ruznak came about 1:15 pm and jumped my car. My husband let my car run to charge it so the garage door was left open. He heard some noise but thought it was me returning home. When I didn't come into the house, he went into the garage to see what was going on and found a tow truck backed up to his car and a man attempting to hook it up. My husband yelled at the man and ran back into the house, grabbed a kitchen knife and went back outside to chase the man away. The man jumped into the truck and sped off. Unfortunately in all the chaos my husband did not get a license plate number or a name from the truck. It was an older model small white tow truck with blue printing on the door. This all happened approximately between 1:30 - 2:00.
We reported the incident to the Altadena Sherriff's Department.I also talked to Ruznak to make certain that a tow truck was not sent in error. They were very helpful and checked with the service tech that came to our house as well as their own service department and Mercedes Benz roadside service. No one sent a tow truck. Also, they only use flat beds to tow.
Now the bad guys are using tow trucks to steal luxury cars. Something new to look out for ...
