Its such a shame that so many cars are getting stolen from there, but unfortunately they are easy pickings if the people dont put alarms etc on the car!! If the police used bait cars in australia surely they could catch some of these guys. It obviously sounds too much like hard work!
Silver-Darkside: I'm not sure if you realise but yours is the third or fourth car stolen from that car park in the last couple of weeks. Can I suggest that you follow the advice of others on here and notify everyone about your car being stolen? Police, Center Management, Today Tonight, ACA etc. Hopefully if enough poor guys in your situation do something about it there might be some sort of preventative or result!!
