Interesting. And would you have any insight into how to persuade the tax official that your car is in 'poor' condition? Or is it a purely academic exercise- if your car has certain extras, mileage it ticks certain boxes and therefore goes up a level, if it does not it goes down a level?
It's hardly purely cosmetic is it? 'Cause if it is, all I have to do is let the children into it for ( in my experience) one longish journey and bang goes the nice clean valeted look!
