yeaahh it really depends on where you live. as in the city. it doesntt even matter where you park. for example, i got my car broken into in the driveway of my house in a nice part of nashville. then i got my car broken into right in front of an apartment on a college campus in boston.
actually, pretty much, if your car is going to get broken into, there's nothing you can do about it. just insure the permanent installed accessories you put into your car. i had a kenwood excelon with the fold up screen that looks like a black panel when off. so it doesn't even matter, it's going to be clear that the radio isn't factory to the trained eye. hardwire radar detectors. sneak wire gps systems. hide the mounts. etc etc etc.
