FP! I say chrome the OEM wheels. I LOVE them, and wouldn't change them for any aftermarket wheels. I do like some of the wheels other XF owners have, but IMO the OEM wheels CHROMED look amazing.
I've heard California is the only place that chromes the OEM wheels (lucky me since I'm in Cali), and if you decide to go forth (even with the rediculous shipping), let me know. My boyfriend and I have been using the same wheel/tire guy for years here in SoCal, and he does an amazing job. He did my OEM wheels, and I've had no problems at all. I can pass along his name/number if you decide to stick with the OEM's.
Good luck!
