(BBC sitcom, 1990-4)

Episode 3.10: Tell the Truth
London Centrewest MA67 (F667XMS), an Alexander-bodied Mercedes 811D, normally operated from Uxbridge garage but here seen with Wilts and Dorset fleetnames added on, is hijacked by old folk disgruntled at having to stand in the rain at the bus stop.

Destination reads 'Poole U5'; U5 was actually the Uxbridge Station - West Drayton Station service:

Not only is the fleetnumber seen, but the legal lettering proclaims it as a CentreWest bus!

“Also seen is a Ford Transit Mk 2 with 'welfare' body in yellow with white roof.” (thanks Geoff Cook)
