The design of the bus is evidently based on that of the Double Decker (albeit slightly wider and shorter), which in turn is based on a Routemaster, but features an open top deck, complete with visible passengers on the seat. Like the Double Decker, the bus is also constantly painted red
Other its appearance, the Tour Bus' performance is the same as that of the Double Decker, being poorer than that of the Coach in GTA 1, but exactly the same as the Coach in GTA London 1969. Being the one of the heaviest vehicles in the game (the same weight as GTA 1 and GTA London 1969's Coaches and the Double Decker), the bus is predictably slow, with a very poor top speed but average acceleration. The bus also possess below average grip and handling, and average braking. Although game files reveal the bus has a lucrative base export value of £1,000, the Tour Bus cannot be exported due to its large size.
