If you know the State it was last registered in you can ask the DMV to do a record search by vin #. Some do it for a nominal fee.You just keep following it forward and back to get the whole chain-of-ownership. Might have to jump to several States to get the whole chain. Might get lucky and the car spent it's whole life in just one State. You should be able to get from the selling dealer right up to the present through all of the prior owners.
