No sure 8k is going to be enough for a white one, unless you find a JDM or galatic mileage 313?
Most other white Zeds seem to have been molested so badly that you'd spend 1000's putting them right (Or a better option, some petrol and a match)... ala the Pistonheads example...
Don't get me wrong, I think white is a good colour for the Zed, it just seems to attract people with a certain "taste", which me no likey!
