Aah. Even worse. It was a consignment deal. Dealer probably never even had title in hand and for all you know the seller is now telling dealer that he never had written authorization to sell at 'that ridiculously low price' and is trying to leverage dealer and your daughter is in the middle of a fight with a private party on the other side who she doesn't know and can't do a **** thing about it. On a consignment sale, THERE IS NEVER A GOOD REASON NOT TO WALK OUT WITH THE SIGNED OFF TITLE.
I know that people who know me believe I don't trust anyone and they are wrong. I trust but verify and only if I can't verify do I revert to the 'not trust anyone' mode. If your daughter waits one more minute to pull the plug on this, she's (trying to think of a nice word). She has your money. Step up.
