I have a special reg on my Aeromax, bought directly from the DVLA, and am glad I did so. I wouldn't buy one from a reseller as they seem to ask crazy money; however, from the DVLA can be quite cost effective and a nice way to personalise your car.
If you can find a plate you like, I'd do it; however, I wouldn't just stick a random plate on the car to hide the age - Morgans do that well without the need of a reg.
