I'm aware that this reply won't be relevant to you any longer but I did want to reply as there is so much misinformation about the topic of what to do if you bought a car with outstanding finance.
Unfortunately, those that bought a car on outstanding finance can be financially suffering for years to come, and without access to the right information people can be left in serious debt.
If the purchaser of the car with outstanding finance has purchased the vehicle in good faith, they can get in touch with an expert solicitor who can help them make a claim against the finance company. The customer is protected by law, so if you aren't sure about your rights, always go to a solicitor.
Solicitors can often advise you of what actions you can take without any initial charge, so you can be sure that the advise you are getting is correct. Have a look at what these solicitors based in Manchester said about the topic, they have a high rate of success and can help people across the country.
