I have a dispute with a main car dealer that I did a part exchange for a new car in june 2008.I received a letter from them in october 2009 asking for the sum of £5000.00 to cover a package for loss of earnings a goodwill gesture pay-out and auctioning costs. They informed me that it was a catergory D write off and was I aware of it , I knew there had been some damage in the past but not to the extent to what they imply otherwise i would not have purchased the car myself , please advise.
