thats weird isnt it

Havent they changed things lately reducing smaller engined car rates? (Ive been off the road for a while so out of touch) my OH said my little 1.3 car is only going to cost me £60 for the whole year? I dont know if he is right

and my bike is going to be the same

I will find out when I go and tax them both in a couple of weeks.
I cant imagine for a minute the PO staff would make a mistake on something like that - but I spose anything is possible - as to whether to enquire? I dont know whether they would then insist on you paying up the rest - probably - knowing them
edit - got side tracked and posted this after you posted jim - ignore me Nutty I havent got a clue
