Car question!

[alendres]

So, I've got my new replacement boot for my car, in the correct colour. But there's no writing on the boot; we had to take the letters off. So I was planning on putting magnets on the letters, and sticking them back on that way. So I have these letters:

SSUUBBAARRUU

Anyone got any particularly witty anagrams? I'm an 's' short for ASS BUS, unfortunately...
