IMHO, if i were to trade-in a vehicle, it's not anyone else's business who i am and why i traded it in.
i would sue any dealer that gave my personal info to a prospective buyer.
now, if it was a private party sale, then that's a face-to-face thing and i, as a seller, would have no problems telling the buyer about the vehicle and why i was selling it.
but since i've never traded in a car and have sold all my previous vehicles myself, i can control what info i give out.
but if i ever did trade-in a vehicle and someone got my personal info from the dealer, man would i be pissed off.
and personally, if i'm buying a used vehicle, if the dealer doesn't have the background info, then it's none of my business and i would never even think of bothering the previous owner.
