So, how do I get some of these screen cards then? What do they look like?

I could have done with one last week when I spotted a silver XF in our local Homebase car park. I just left a note on the windscreen saying something like ..'nice car I have one too' & gave the website address.

Not many Crossfires in my area..... this was the first one I've seen round here. Rare as hen's teeth!
