How do you go about it and what do you need? I need the tax disc by Friday if I do it today, WITHOUT FAIL!
Cheers

Same as any other car sorn or not.
Just take the V5, a valid MOT certificate and Insurance certificate to the post office
If you have the sorn notification letter with the barcode on it, it can help, but you dont need it. Same as you dont need the tax reminder to retax a car.
