The Register doesn't shed any light on this question. There are four cars, AK2000 / AK2001 / AK2002 / AK2003, all LHD, two for US and two for Germany. AK2000 shows 1993 build date, AK2001 shows 1995 build date, AK2002 shows 1994 build date and AK2003 shows 1995 build date. The cars with AK numbers starting with AK1xxx run either side of these four build dates making it even more confusing.
