Car dealerships - Never cease to amaze me. And they always whine about not being respected by the public. Based on the facts you describe this transaction has been consumated by all parties. Look at it this way, I trade-in and buy car at a dealer. Then a week later call and say.....Um, excuse me can you send me a check for $3,000, I think my trade was worth 10k not 7k. Thanks. I am sure their response after laughing a lot would be and rightly so, sorry no-can-do. You need to see an attorney today. I look at this way, they have shown extremly bad faith in this action, when this happens do not put on your nice guy- Mr. optimist hat. They are the experts, they have most likely done this many times before. I think they may sell or wholesale your trade then hold up your title work. Then you can't get your old car back and you can't drive your new car. Then your lender starts calling because they should have the title by now. If they don't get the title at some point can ask to have the entire loan paid back. And while this seems odd based on the way the system is set up it is true. What should happen is they transfer the title to your name with a lien listed from your lender. What they are doing may be criminal or at least some type of civil tort, ie threatening to try to damage a legal contract unless you pay more. Back to my first comment. I know nobody likes to pay an attorney when they are the ones getting hosed, but if this deal falls through, you will wish you had spent that few hundred dollars. The attorney should have you call them and ask for a faxed note with the request. That way you have documented proof of what they are trying to do. a>
