When you dont tax a car you have to fill in a SORN certificate to state it is off the road but because Kris gf sold the car and did what she should by filling in her part of the form for selling it then she wouldnt have filled in a SORN because the car wasn't hers anymore, besides that...the car got a parking ticket which would have proved to them it wasn't in the back garden.
oh i see-----------so its a case of finding the buyer and getting him to pay his due's then m8
