That last only other XF that I saw was a black coupe, about 2 weeks ago, as they crossed in front of me at a traffic light In Greenwood, IN. They were waving frantically as they passed by.

Since a number of XFs are being garaged for the winter, I'm sure sighting will decrease to darn near zero. Then again how much closer to zero can you get? Since sightings are always near zero anyway.
