We have vanity plates for the sheer hell of it, 'cause they're so cheap here

SG, round here, half of the high school students (=4th year thru upper 6th, dunno what they call them now) have cars, never mind college (=uni) kids. It's a cultural thing, plus we live near motown -second-hand cars are cheap and plentiful as all the autoworkers are encouraged financially to change their cars regularly.... this may change....
