What tax rating disc will yours be. If you bought in 2001?

Question

The government say poorer families will buy cars with low LED shows they don't live in the real world. The poorer people buy the cheapest second hand cars. And it is unfair to change the tax after someone has already bought a car. If they want to do it it should only be done on new cars sold now. Or we won't buy anything in case they tax it after you have just purchased it.

Answer 1

Isn't that the idea?  It's the most effective way of cutting carbon emissions.
