I would be pretty certain that it was originally a VAG UK car/Press car. In the service book, it will have the stamp of the supplying dealer inside the first page. If it was a VAG UK car, it will have the VAG UK Milton Keynes stamp.
Phil Short's old red 20V was a G+++ KVV reg originally,before it had his plate on it.
There was also a Glacier 90 quattro 20V with a G+++ KVV reg used in a CAR Magazine Giant Test in early 1990.
A lot of the high end Audis of that era were VAG UK registered, especially the V8s, 100 Turbos etc.
