My buddy thinks he got screwed buying a car off of private seller for this reason:



He went and bought a car, Dude gave him 2 keys with it. He think's the dude used another spare key to steal it back.

Change locks, or just make a security switch or something. You can do that by wiring a toggle switch to your fuel pump. Some people I know have done the Cut off switch to the ecu's too. Just hide it real nice.

Always car fax that shit.

I've heard nothing but bad things about salvaged vehicles. Good Luck on your search.
