Some routes were operated by a fleet of 70 Dodge minibuses, whilst others used double deck buses, notably 25 secondhand ex-South Yorkshire Transport Volvo Ailsa B55 with Irish-built Van Hool-McArdle bodywork.
Ayrshire independent operator A1 Service, whose operating area included the Ailsa plant in Irvine, also purchased several of the vehicles new, increasing its fleet where it could through the purchase of used vehicles.
