Hi all, I have noticed there are different tax rates for identical vehicles registered in 2008. If you own a Grand Voyager 2.8CRD 2008 please share your road tax amount below. DVSA website says the vehicle emits 225g/km and DVLA says it emits 250g/km. DVLA can't answer why there is different information.. The difference in rates is quite significant £305 and £520. What's your road tax amount?
