Special narrow bodies built for use on the Channel Islands retained the pre-1976 style grille until the end of production.
The Dominant II (introduced in 1976) had a deeper windscreen, rectangular headlights, a different grille and a smaller, flat, single piece rear window.
The small high-level windows were designed for SBG's overnight Scotland to London services where quietness was more important than passenger views, but nevertheless some other operators did buy the Dominant III as a touring coach.
Many Dominant bodies were built to a dual-purpose specification featuring bus-type doors and other modifications to make them suitable for OMO (one-man operation) stage carriage services, and thus eligible for the British government's bus grant which subsidised the cost of new service buses.
Some such bodies were actually furnished as service buses with low-backed bus seats, in which form the model was known as the Dominant E (again with mark number where applicable).
In 1983 the new Duple Laser and high-floor Caribbean were launched as replacements for the full-sized Dominant coach variants and the Goldliner respectively.
