 In the late 1990s Clydeside was purchased by the Cowie Group, who rebranded the operation Arriva Scotland West.Arriva and Dart, both realising competition was uneconomic and couldn't last, reached an agreement and Arriva bought a 25% stake in Dart.This resulted in Dart and Arriva scaling back competition, Dart focusing on the Gryffe area services and motorway express buses, whilst Arriva pulled out of the area and concentrated on local Paisley business, that in turn Dart had stopped operating in.
