I’ve got six cars. One is under restoration which should take years to do, and one is a Triumph Herald 13/60 estate. I use the Triumph to carry my five dogs out for shooting or just general dog walking. Last week I received notification of the road tax for the RS6 ; it was £600. My other cars have significantly larger engines so what will their road tax be ? I’ve decided to SORN the RS6 and put myself on the insurance of my wife’s Alfa Romeo. For the first time ever, the cost of road tax has made me wince. Using a car has now become seriously painful..
