Soon after introduction the vents above the front lower windows were filled in as shown in this example. The baseplate changed from DG41 to DG41-49 in 1991. The method of riveting the base to the roof was modified during 1993, the rivet head at the base was sited in a plastic washer.

Initially the body had a large rear flange which completely filled the body overhang. When the DG24 and DG25 Rolls Royce models were introduced in 1987, a new smaller flange was introduced to allow the chassis to become a common component as shown in this example. A change in baseplate text, DG18-19-22 was made in 1986, followed by another change, DG18/19/22/24/25 in 1987 and in 1990 to read 18-19-22-24-25-38. A steering wheel and seats were added in 1991.

The original roof had a smooth underside which was changed after only approximately 1,000 models. The new design incorporated a ribbed underside to prevent turbulence in the casting process.

The introduction of downstairs seats was made in 1989. At the end of 1997 new tooling resulted in the bulkhead between the lower passenger saloon and the drivers cab being removed and the new lower deck seating moulding incorporated for the first time a driver seat.

The chassis up until 1989 was produced in equal numbers of thick and thin wings (or mudguards as we have called them). Early baseplates ranged from DG10-DG12 and DG10-DG12 in box but in 1989 it changed to read DG10-12-34-35

Soon after production commenced the connection of the platform to the body was strengthened adding two braces. This earlier model is quite scarce. In 1986 the body casting was modified  to include a side advertising panel on the lower edge of the central windows. Lower deck seats were fitted in 1989.
