He's wrong, it's vehicles with greater than 225g/km of CO2 emissions, and it has to have been registered after 23/03/06.

A mate seems to think that all 4X4 vehicles are going to be £400 to tax from April.
I've got a 99 Jeep Cherokee.
Pretty sure there would be outrage if the goverment back dated a tax hike like that to older 2nd hand vehicles. For a start that would seriously devalue a lot of 2nd hand cars!!!!
They increase the price of tax on my 20 year old cars every year
yeah by £5/£10
not £200 !
