The latest changes to Vehicle Excise Duty have thrown up some serious anomolies. I do wish that the chancellor would leaves things alone and not keep changing everything all the time. I bought a new car last summer and specifically chose the version of the car that was below 225 grams of CO2, not least because of the VED bands. These have now been changed again and the increase in my 198 g/CO2 car is from £210 to £260 in 08/09. This is virtually a 25% increase for a car with not unreasonable emissions. The higher band G increase is only from £400 to £410!
I really don't think it is reasonable to apply these changes retrospectively in this way to purchase choices made under the previously announced bandings. Please please please leave things alone now so that we know where we are.
Furthermore, the VED process ignores the most important variable - miles driven per year in a given car. Other variables include style of driving and quality of maintenance etc, but these are even harder to measure.
You can have a very inefficient car that only does a few miles a year, or a low emission car that does many thousands of miles. The low emission car polutes more!
In any event the only truly sensible and fair way to both raise tax revenues and encourage environmentally sensible behaviour would be to scrap VED and increase tax on fuel. This then captures fuel efficiency (the primary contributor to CO2 emissions), mileage driven and also driving style etc as the more efficient drivers use less fuel and incur less expense. Simple.
It must also be true that if everyone ends up with a zero rated VED car then the cost of managing the VED process is loss making - so why bother? But then that would mean a government withdrawing a tax/process! Just think of the trees we could save by scrapping VED (including all the paperwork involved)!!!
The real reason that this simplification would not be done by this government though is that they want to micro-manage every area of all of our lives.
