the thing with reg plates its a very personal thing.
When i bought my 3dr it had its original plate D99 MAT - the guy i bought the car off told me it was a private plate so i ended up paying a bit more for the car.
Had RegTransfers or some similar company value it and they said they could get me close to a grand for it so i let them advertise. A year later not even 1 phone call
Ended up putting it on ebay and it sold within a week for £700.
My D16 VRS was only £250
