I used to have L7 HOG on a Harley of course!!
When I bought the Morgan I bought L3 XAN and P3 XAN both bought from DVLA, £200.00 each I believe, P3 was on the Morgan and L3 is on the daily runner (XAN is the closest I could get to IAN)
The idea was to hide the age of the car and I personally think that the less numbers on the registration make the car look neater.

That reminds me; I also have V2 NUT on my motorbike.
Originally bought direct from the DVLA for £249, when they first went on-line in 2001. At the time the bike would have worn a '51 plate, (which would have looked like a dinner tray on the back mud-guard), so I searched the DVLA site for any simple prefix plate and V2 NUT was available. Initially it went on my Moto Guzzi V11, before being transferred, first to a couple of Ducatis (1000 Sport & 999S). Now resides on my current bike.
