New Black on Black Car, vanity plate ideas?

Ive come up with some ideas but im looking for some more clever options to play around with. ive thought of ZIMZWHP // BLK ICE // BKMAMBA. Which ones does everyone like? My car is a black volvo s60 with black leather interior. So something with black, dark, or night would be nice. thanks for everyones help!! oh and it can only have 7 letters.
