Have you bought a higher-emitting 10-plate car and escaped the showroom tax that's coming in on April 1?
Or are you in the process of buying a big car and expect to pay this one-off hike in VED?

What is the showroom tax?
Cars bought on or after April 1 will have to pay a one-off so-called 'showroom tax'.
This VED (road tax) rate applies only to the first year of ownership. In the second year VED road tax rates will revert to the regular rate for that vehicle.
