So I just found this out at the weekend, and while many of you probably already know, it was news to me!!
Vehicle excise duty is changing from 2 April. If your new car is registered after that date, you will pay new rates of tax. For the most efficient petrol cars, these represent a substantial hike on current costs. A band B car is going to increase from £20/year currently to £140!
What is more, the rates are active for a time into the future - so if you buy a car on 2 April, you'll pay £140 every year, whereas someone who gets the registration through before 31 March will continue to pay £20 for some time to come. Over a few years, this means the cost for those who like efficient petrol cars will be hundreds of quid extra.
While I support tax rises, I do think it's bonkers to hit the most ecofriendly petrol cars the hardest and let the more polluting cars off the hook!
