Sorry man. Car thieves suck. Nearly every car I have owned and left parked out has been broken into or damaged in some way. In college I had a van. Inside there were 4 cheapo bookshelf speakers, Alpine stereo, and a $2000 set of motorcycle tools. Thieves broke in, took the speakers and left the rest.
No rocket science in their future I guess.
As of about 12 years ago... Garage space first, then nice car.
