I'm sorry this happened to you. Like you, I didn't even know until reading your post that this type of scam existed. Shame on the loan companies and shame on JD for using such a loophole. Thanks for your posting. Perhaps the lawyer will offer remedies, I hope so.
But regardless of whether he does or not, I urge you to fight for your rights - all of our rights. It sounds like there are laws here that need to be changed, and it also sounds like the finance companies are taking advantage of those laws at the expense of the general public.
In my opinion, the people making the loan should be the ones responsible for protecting their own collateral. It shouldn't be up to some unsuspecting buyer to protect the finance company against some loan that they shouldn't have made and that a subsequent buyer has search out or lose out years later.
This is an example of a type of misplaced responsibility that could end up damaging our the whole concept of private ownership.
Hopefully this will get straightened out.
