Another question about car taxing, il try to make more sense?

hi why dont you ask him to tax it for you as the car is still in his name then you give him the money for tha tax when you get the car this is what i di last week the car had 12 months mot but no tax and as i coudnt drive without tax and coudnt get the tax untill the logbook in my name he went to the post office and taxed it for me then i gave him the money, he was able to tax it because he is a trader hopes this helps
