Hi ,
I have just quickly read through this thread and looking at your Bill of Sale it does not mention the correct amount of the loan this means that it is unenforceable therefore the loan is not secured on your car.This means that they cannot seize the car as they will be breaking thne law.You should hide your car or park it somewhere else and consult a solicitor if you are entitled to legal aid Stephensons Solicitors Welcome - Stephensons Solicitors (Leigh, Wigan, Manchester, Bolton, St Helens) - Family, Commercial Law, Conveyancing deal with these kind of issues and I recommend that you contact them anyway.With regard to your PPI you should contact The Finanancial Ombudsman
Financial Ombudsman Service and ask their advice.
