To a large extent, this is because the X-Type's credentials are in doubt, as it's based on a less-expensive sedan Ford sells in Europe called the Mondeo, which was briefly sold in North America in the late 1990s as the Ford Contour and Mercury Mystique.
What's ironic about this is that the Ford Mondeo seems to be a much better car than the X-type. It's got more room too! This is also true with the Opel Vectra and SAAB 9-3 IMHO.
