I moved to Germany with my #1, having only seen 3 in Oxfordshire(one was a #3), I saw 2 car transporters full of #1/#3 driving through Holland and on my first weekend in Aachen saw a black #1. I'll be back at xmas hopefully with a german licence plate.
I think I've seen 5 on the road, including one on the way home today. I also saw a car transport full of #1s down near Bristol a couple of months ago. Still waiting for mine to be delivered!
