The company is attributed with starting a bus war with the main operator of the area, Clydeside Scottish.
The company started to expand, and in particular grew a strong presence in the Gryffe area around Johnstone, Bridge of Weir, and Kilmacolm operating the lucrative motorway express buses to Glasgow in competition with Clydeside Scottish.
Clydeside also introduced its own low cost minibus service F&L around Paisley, in order to secure a larger share of the market from Dart.

[1] Dart concentrated on fleet improvements and bought progressively newer vehicles and expanded its local buses providing links that Arriva didn't operate to places like Pollok.
