You should really put some sort of effort into securing your car when you put some decent money into it. A 240sx is the easiest car to steal in the world. The door lock is cuped so you only have to stick a coat hanger in between the flimsy easily bendable window and then pull the lock twords you and its open. put an alarm on it too, their are cheap ones out their if your on a budget. some sort of engine kill shit too for if they do try to start it. just think of how easy it would have been to stop him with a remote kill switch. I think you said you saw him taking off in it in a post on here. You could have pressed the button ran up to the vehichle while he franticly tried to start it and then drag him from the car and beat his ass...then tie him to the toe hitch on the back and drift around a parking lot till his body has no skin left on it
