100 ways to disappear and live free
I. DISAPPEARING
If you need to dump your car, sell it yourself to a private party for cash.
Be very careful not to reveal anything to this person about your real plans or reasons for selling. He would be an ideal source of information of this nature for snoopers, thanks to the efficiency of auto registration systems throughout the country. The buyer will, of course, be an excellent place to dump your *fake* information...
Once you relocate, should you need another car, pay cash for it even if it represents lowering your "status". Delay registering it as long as possible. By the time you do, hopefully you will have established a new identity completely unknown to the last owner of the car.
