Rob i dropped on mine about 15yrs ago i followed a car with it on and stopped the driver and asked him if he wanted to sell it ! he did and i gave him 800 squid for it !
i joined CNDA and every year they send you a valuation!
my plate is worth £10,000 but only to someone with my initials and who wants it!
so it's worthless realy if you get my drift!
ps buy one anyway as it does take the year off what you Ride/Drive
