My 02, good luck getting him to answer any questions regarding the mishandling of the XF under his watch. It is my understanding that DC is still sitting on a bunch of 06's with some going to rental fleets. So you can ask him what's DC's strategy for the future of the XF?. The car I saw at the Detroit autoshow last week was in fact a 2006 model, where are the 07's?
Anyway like I said before good luck and enjoy the show, you will be in good company but don't expect too much from Dr ZZZZZZ.
