Any rights in TN for purchasing a 'buyback/lemon' with a branded title which the dealership did not disclose?

In the car business this practice is sometimes called "lemon laundering" and it goes on more often than most people think. I don't buy what the dealer is telling you. Besides, if there was a stickie post it note on the title, that would very likely have been removed when they got the title because the dealer then had to go process that title into one that had their own dealership name on it. On top of that, whether they were "informed" or not has nothing to do with what they "informed" you of when you were buying it from them. If the dealer was duped, then they have the right to go back on the person they bought it from too, but that also has nothing to do with you. The real question is whether or not the dealer told you the truth about the vehicle. Many states have a law that says if you buy a motor vehicle and then get the title later and there's some kind of brand on it (like the lemon law or odometer rollback, etc) then you may have the absolute right to cancel the sale if you try to do it within a short time after learning of the branded title. Regardless of that, your facts sound like the dealer is likely liable to you for at least your damages (the loss in value of the vehicle) if not more. To find out what your legal rights are for sure, you need to talk to a Lemon Law attorney near you. Try calling your local attorney bar association and asking for a referral to a Lemon Law attorney.
