If you track back through threads you will find that I was stopped by DVLA who argued that my car was untaxed despite the fact that I had a tax disk and the receipt from the post office for the payment.
When I phoned DVLA they had the car registered to me but listed as not taxed?????
So the other week I went off to the post office, tax disk in hand, and renewed tax no problem. I have yet to check with DVLA to see if they have got it right this time.
Interestingly, and I was up for the fight if they did, they did not decide to send me a letter, demand for tax, or a fine, despite their claim they do it all automatically.
The system seems to have holes in it!
