I drive a 2016 Dacia Logon. It is the least noticeable car in the car park. Massive boot. Currently road tax is £20 per year. £1.75 per month on DD.
My theory is that if you can't change the tax on a car because of what it was when it was born then you can't **** about with my pension age after I'm born either and can't keep putting up my taxes after I'm born either. The fact that they do keep increasing my taxes after I'm born means they can and should be able to do the same for vehicles
An Act of Parliament can do anything. As yet my Dacia is £20 a year road tax. Won't vote Tory if they put up the tax, but I might change the car.
