Today's Wall Street Journal has an article on how Chrysler is leading the Big 3 in incentives this month. While the XF is not mentioned it does state that DC "...is pricing newer models cheaper than the older ones they replace, and offering many more options on the standard versions."

I don't know how this relates to condensation but would be interested in that again. I have not experienced this phenomenon but have not driven in much, nor heavy, rain but will be alert to this potential issue.
