Hello Tony
The X 230 ran from 1995 -2002
the The X244 base vehicle ran from the facelift in late 2002 – until early / mid 2006 when it was superseded by the dodgey X250, which was the base vehicle for new 2007 season motorhomes. That is when Hymer decided that sales/ production costs/ profits made it uneconomical to re- tool for the very different new base vehicle dimensions.
The Exsis was only built on the X244 – mine left the Hymer factory March 2006
