That is nice advice from your friend, and I'm sure there's some validity to that. That being said, I've had a personal plate on my car for over 8 yrs, and knock on wood, never any problems. I park everyday at my office parking garage during the week and regularly park at shopping centers on weekends. I think if someone has decided to steal or do something to your car, it will happen regardless of what plate you have on the vehicle at the time. It won't stop me from doing what I want with my car cause life is too short. So, I say get what you want.
How bout 'LIL BSTD'?
