The missing "L"

I searched high and low but couldn't find the missing "L". I thought I had found Mr Blip but no, it was only Mr Bip in his Bentley. Excuse the rather lopsided shot but I was worried Mr Bip would come back and shout at me for photographing his car.

Parked on double yellow lines with a number plate like this on a red Bentley. What kind of man owns a car like this?
