Andy, I've seen that Britax Cooper (I think it was in Mini Magazine last month), that's what got me interested in it so I made my own with the Mini Selecta and found the decals on Google. I'm reading a book about Coopers at the moment that makes mention of the Britax Coopers and the black Cooper Car Co ones too.
I think I've seen Haggis around as well (I'm in Dingwall), I have to say he (he, or she?) looks superb and I love the 1275GT you've got above.
The white Mini in my sig is the plan I have (well the first one anyway), but a lack of space at the moment is stopping me, one day though, one day
