Most states require that the seller deliver a title to the buyer within a certain number of days and that if your name is not on the title then legally you have no interest in the vehicle. As for the dangers of getting a used car and what you can do about it, that’s another question. In a used car sale, your legal rights are mostly determined by the paperwork that you sign. Look to see if anything was written down about any kind of warranty or guarantee or right to cancel the deal. But that’s not the end of it. You need to talk to a local Consumer Law attorney who deals with this kind of case (it's called "autofraud" or car sales fraud). Call your local attorney's Bar Association and ask for a referral to a Consumer Law attorney near you or you can go to this web site page for a Free Online 50 State National List of Consumer Law Lawyers (http://www.ohiolemonlaw.com/ocll-site/ocll-locate_local.shtml) and find one near you (lawyers don’t pay to get listed here and most of them are members of the only national association for Consumer Law lawyers, NACA.net). But act quickly because for every legal right you have, there is only a limited amount of time to actually file a lawsuit in court or your rights expire (it's called the statute of limitations), so don't waste your time getting to a Consumer Law attorney and finding out what your rights are.
