That's not actually a thing.  What you're talking about with the car is the doctrine of replevin, which allows the owner of stolen property to recover it.  It's subject to a host of limitations, including the fact that it doesn't apply to money.  There's also exceptions for good faith purchasers which would apply to the stolen car.  Your example is wrong.  If the purchaser of the car didn't know it was stolen (and didn't have reason to suspect that it was), they may actually have a good claim to keep it.  That doctrine gets more complicated than the character limit here will allow, so I'll leave you to look it up.

Generally speaking, it's good to recognize that "the law" is actually a thing which has meaning and effect outside of your individual belief.  The fact that you may wish for a certain thing to be true "as a matter of law" doesn't actually make it so.
