^^^^^ like he said. Or pull the dizzy. If they come with a tow truck or trailer or a rope its a lost cause. No alarm= easy target for you and not the theives. One less thing they have to worry about. And it won't make a sound.
Theives +1 ,you -minus one. I would keep the car blocked in. Out here in calie if you put your car in the paper. Most insurance car companies void your policy unless you add futher coverage. My customer got screwed this way. Had a fixed up teg in the paper. Had people come see it. 2 days later it was gone. Said but true. Theives shop the books too. good luck
