It's always easy to say "coulda, shoulda, woulda..." but until your actually in that situation in most cases would wouldn't be the winner.

That does suck man, I had my wifes '04 is300 broken into back in '05 and it was a few thousand $$ worth of damage not including what was stolen. My truck was parked right next to it so that night all my stereo stuff came out that night just to play it safe, especially since they got 7 cars.
