I have just part exchanged my car today and took the tax disc out as there is still 7 months on it to run, the one I have bought came with no tax so I had to pay for that on top of the car price. I have just notticed a message on my answerphone from the car dealer asking me to return the tax disc from the car I traded in as it was sold with the car. The tax was never mentioned and it is not on any of the paperwork, does anyone know how I stand? I have always taken the old disc out for a refund when I have part exchanged before. Anyone any ideas please?
