just get a chipped ignition & chipped key? i think that will work and get lock cylinder from a different car and mod them to fit.. that will throw people off like a bitch.. now as far as the stuff you leave in the car... well theres no stopping that anyone will break a window and grab whats in sight within seconds then split. you can also take a big fat ass chain and a big fat ass pad lock and lock your clutch brake & throttle together tightly. no ones can fuck with that.
