The Pollok and Darnley routes were express services which made good use of the new M77 motorway in the area and used new low floor vehicles. However, due to First Glasgow's new operations in Stagecoach's key Ayrshire and Fife markets Stagecoach decided to scale down operations in the area. It acquired Arriva Scotland West's 49% stake in Paisley company Dart Buses. Dart took over operation of the Pollok and Darnley services, which were closer to its base in Paisley and more in fitting with the rest of its west of Glasgow motorway express services. Stagecoach supplied vehicles to operate the routes, which continued under the "Stagecoach Glasgow" livery and brand, while several Dart vehicles were repainted into the Stagecoach corporate livery. It is unclear as to when Stagecoach acquired the stake in Dart Buses and as such it is likely that the company operated the Stagecoach services while Arriva retained their stake. Dart Buses ran into financial trouble early in the new millennium and without notice suddenly ceased operations overnight. First capiltatised on the collapse of Dart Buses and registered the defunct company's motorway services before either Arriva or Stagecoach could, and as such Stagecoach decided not to re-start operations.
