The S2 has the default plate on it as I did not think it needed anything to make it more different!
The Coupe was gifted a private plate by my wife for my 50th birthday. My initials so personal.
I bought an Audi RS6PE a few years ago. My wife hated it and got me B17 EVL (BIT EVIL) for it.
In return I got LE55EVL (Less Evil) for her mini. They looked quite funny on the drive together.
I sold the Audi but moved the plate through my daily drives and still have it on the AMG now where it works given the noise the V8 makes.
w.r.t. to MOG, it does at least remove some of the "what is it?" questions you get as it gives them a clue!
I think a Morgan and especially the Coupe can carry a name type of reg as it has so much character as a car?
