I was thinking about the possibility of making the Emperor's shuttle look fancier, like making it look really clean and having a grand looking emblem on the side of it, but on the other hand would that really be what the Emperor would want? It would make him an attractive target to any nerdowells who are around, whereas a standard, weathered looking shuttle is inconspicuous.
Oh dear... Now I've gotten myself on a train of thought that I'm having trouble leaving! :(
