First, from my own readings, I think most of your questions have indeed been asked and answered before. Take your time and do some looking around this site. There is a wealth of information here. Heck, were it not for this place, I'd still be driving around with dirty front wheels, visor airbag warning labels, and Chrysler emblems.

And as a somewhat recent member of the "club", I'd dare say it is unlikely that anyone here would discourage you from joining in on the love affair we all seem to have with our beloved XF's. And I for one, would welcome you to join in on the fun in owning one and participating here (pre- and post- ownership).
