If someone wants your car they'll just bring a flatbed and tow it away, ain't nuthin gunna stop them besides a Marine Expeditionary Force standing guard around it.
I wouldn't want LoJack on my car either. If it's stolen, it'll probably be stripped or wrecked or messed up some other way and I wouldn't want it back anyways. Let em keep it, I don't wanna deal with the hassle of getting it fixed, just give me my money and send me on my merry way to the classifieds in the newspaper to find another car.
