Although it shared most of the same components and chassis configuration as the Premiere, The design of the Excalibur differed by having a distinctive 'swept-back' fascia featuring a raked windscreen, and internally, the Excalibur featured a plug door as standard,[11] as well as including reclining seats with optional drop-down armrests and luggage hooks, enclosed luggage racks and pull-down sunblinds as standard, as well as a Blaupunkt speaker system.

[12] The Excalibur was also bodied on the long-wheelbase Volvo B10M SE variant, allowing for an underfloor luggage compartment, accessible by lockers on both sides of the coach, to be equipped as standard when compared to conventional B10Ms.

[13] The Plaxton Prestige was a 3.7 m (12 ft) left-hand drive export version of the Excalibur that was built on a tri-axle variant of the Volvo B12 chassis, uniquely utilising a 'lowcab' design that enabled the driver's cab to be 470 mm (19 in) lower than on standard B12s.

The body and chassis combination was briefly marketed by Volvo towards French luxury coach operators, competing against established designs by Jonckheere and Van Hool.

The Prima was marketed as a budget version of the Premiere for price-conscious operators: although it retained the same design and framework as the Premiere, standard features of the Prima included 57 seatbelted and reclining seats with fixed footrests, ribbed cord interior trim, solid rubber flooring and an overhead luggage rack design reused from the Paramount.

[18] The Stagecoach Group was a highly popular customer of the Premiere Interurban, choosing to standardise on it as its standard coach body throughout the 1990s; a two-year contract placed in August 1992 worth £7.5 million (equivalent to £19,604,000 in 2023) to supply 150 of the type, 100 on Volvo B10M and the remaining 50 on Dennis Javelin chassis, was Plaxton's biggest ever order during a time of financial difficulties for the manufacturer.
