Towards the end, when Number Six wakes up and starts running around the mock western town, his blazer changes from buttoned to unbuttoned and then back to buttoned again. This occurs when he runs into a building and then runs out of it.
Toward the end #2 is driving one of the Mini Moke taxis. The license plate on the front (HLT709C) is a regular British plate, not the usual Village ones that just say "Taxi".
