Been on them a couple of times, try and use public transport if coming back from airport as taxi is £30. I usually travel by myself. But late at night its taxi.Seen pictures of them on the 88,89 and X3 so far. Never been on one of them before but they do look like pretty good buses to use as a passenger
I think they suit dark colours like blue, green or black, never been on a normal specification one, though you see fair few down south.
