so i just tried taxing my car online and it wont let me do it, so i ring the DVLA to find out what is going on, and it turns out because the previous owner had the car off the road for 2 years without declaring SORN there is a fee to be paid for the 2 year gap, however they couldnt tell me how much the fee is, has anyone else ever had this problem and what sort of fee am i looking at getting for this???
