I hate to be the bad guy here, but who's idea was it to have that stuff sitting in sight in the car? Before I dropped my car off at the shop for the engine change, I pulled the stereo, rear speakers, and CB out, and ran some lose wiring out of the stereo hole so it looked like the unit had been ripped out. I also saved up a couple week's worth of fast food bags and cups and dumped them on the front and rear floor and on the back seat, along with some empty soda cans and some old newspaper circulars. In short, I made my car look as unappealing to thieves as I could get it, and anything worth stealing was locked up in the trunk.
