I recently had the wheels refurbed on the wife's XF. The centre badges were intact but tatty, so I resecured them to the centre caps and bought a set of these;

They aren't cheap, but worth it as they certainly make the effort of getting the wheels refurbed, complete.

I hadn't intended on using the badges for the bonnet and boot, but did and they look great, too.

There are loads of photos on the thread that's linked, but if it ever stops raining, I'll take some of them on the wife's car and post them for you to see.

Hope this helps.
