L15TEN for the exhaust note !
S111TAN (put a fleck of black paint to make UN out of the 111) and you have sun tan, good for an open top but bad for your long term health.
I like these - I have been trying to be more creative (without spending thousands) but I'm a little limited having only A to F as initial letters to play with. (Yes, I know there's 'all' the suffix plates but you can't pick and choose with them.)
Now the orange and white plates have been on the car for a little while I am getting used to them so I'm leaning a little more towards "interesting" than "black-and-silver-and-never-mind-the-number" at the moment.
Could all change again though.
