better not phiebert. I still remembered back in 11 or 12 years ago when i was still living in the US, i've brought and installed one of those voice "the car had been tampered with, 5, 4, 3, 2, 1......weeeeeeeeeeeeewwwwwoooooooooooooo" type of alarm system in my porsche. The very second day, it had a long key scratch from head to tail. Really sad...guess it attracts too much attention ; )
