used flatter service units with eyeball vents and a flat lens on the reading light. The Supreme Mark IV was introduced to the market at the International Motor Show at the National Exhibition Centre, Birmingham in 1978. The main update was that construction was now all steel, frontal design was completely different from the past 14 years. The headlights were now rectangular and mounted above each other with side lights and indicators in the same cluster. The grill was not so prominent and various options were available as a package. So now the range consisted of Supreme IV, Supreme IV Express and Supreme IV GT. The GT option ushered in a distinctive grill design with a smart dual chrome flash, tinted windows and better sound system and soft trim to the ceiling to name a few "standard" extras. Supreme V had a completely different rear design showing the styling of the next range that was probably under development. Tall heavily featured light clusters that were tinted to look dark were fitted vertically between the boot lid. The rear window was a one piece design. The seat backs were no longer visible from outside the coach. The rear nearside had been tidied by removing the smaller windows. The improvements were also copied onto the high floor Viewmaster model with the exception of the shallow rear window. The Supreme was also manufactured as a semi-integral on a DAF chassis. Around 20 were built. They were rear engined and the rear panel design was different from the Supreme V as it has vents and had odd shaped moulding around the rear window. As a semi-integral the body was required to support the full weight as there were no chassis members to support the body. Opening the side lockers luggage could be piled in one side and extracted from the other as nothing was in the way so it was very cutting edge technology. It is said that 2 of these survive today. The bulk of the 20 were exported, mainly to the Netherlands, the left hand drive version had a tapered front to meet Dutch swept turning-circle requirements. Final Supreme offering was the Supreme VI. This model was the least successful Supreme being an option for one season alongside the Supreme V. The panoramic windows had been replaced by a higher window line that was better suited to the long distance market. Around
