We bought our van from a dealer which has gone bust, and since
trying to sell our van we have found out that there is finance owing in someone elses name and can't find out how to sell it. I know the finance is owing to Black Horse, we paid cash for the caravan.
I am not sure what the legal situation is here. The best advice I can give you is that you try the Citizens Advice Bureau. I am pretty certain that they will be able to help.
