My girlfriend just got an '03 yellow convertible and her new plate is "BUZZIN". Massachusetts has very restrictive rules about vanity plates and don't allow them to begin with a number nor can you have 2 letters, a number and some more letters. In addition, we're only allowed 6 figures. Makes it very difficult to be creative!
One that I wanted to put on a '74 roadster we used to have is "WAY2GO". That's when I learned about the number not allowed in the middle.
Good luck! It's always fun to think of an appropriate vanity plate.
