I was listening to a radio show hosted by Jerry Reynolds a well connected and prominent promoter of Fords and he is under the impression that Ford is not going to put any real money into developing the Expy any further. He says that it may even go away as a discontinued model soon.
If you review the sales figures for the Expy they are shrinking to the point where they may no longer be a profitable vehicle for Ford to produce.
Their US sales figures are:
2002: 163,454
2003: 181,547
2004: 159,846
2005: 114,137
2006: 87,203
2007: 90,287
2008: 55,123
2009: 31,655
2010: 37,336
2011: 36,287
Canadian sales don't add much to these numbers with around 1500 for each of the last 4 years.
