I was surprised to learn of a McCoy in The Netherlands last month (click here), but it's not the only example of the species outside of the UK. Raynald Claudine has one in Brittany, France and recently took part in the car in the Florio Cup in it; a local hill climb in Saint-Brieuc. The newspaper Ouest-France wrote the following: "For almost forty years, Raynald Claudine has been passionate about the original Austin Mini, even to the point of setting up a veritable museum to its glory. During the Coupe Florio, which will be held from September 9 to 11, 2022 in Saint-Brieuc (Côtes-d'Armor), it will be possible to admire his latest acquisition: a car produced in only 83 copies and unique in France."
The McCoy wasn't the only Mini variant entered in the Coupe Florio as there was a Mk3 Mini Jem on Luxembourg plates also. I don't know how the cars did in the hill climb, but I understand both of them finished.
