I've had discussions with the Mrs about this.
I previously had a personalised plate on my Jag (my initials) but nothing since. I've toyed with getting a 'CWP' reg for my Mog (Grandads initials) but my Mrs is of the opinion 'why spend money on something that you get for free' and over time, I've come round to her way of thinking.
I have an old Uni mate called Morgan, and everyone calls him Mog, so not unique to the car world.
