I agree. That's stupid advice to give. Just take the necessary precautions that does NOT involve arming yourself and laying in wait. Get any security devices you can from alarms to kill switches to steering wheel removal kits.
There is no car worth your life. It doesn't matter if you've put blood, sweat, tears OR money into it. It does you no good when you're sitting in jail doing time because you shot someone trying to take it. How cool is it when you sit with your cellmates talking about how you have a bad ass Civic waiting for you when you get out. You have a bad ass Civic that you'll be trying to sell because you can't get a decent job because you have a record.
Over what?
Ya dig. Later, QD.
