I've seen a few posts about towing with a Mini Countryman.
Picked up a Troll 535 today with my Mini Countryman, F60, 2018 Diesel 2 litre automatic Cooper D.

It towed very well. Most of the journey was on the motorway and you could feel it was there but no snaking or instability at all. 65mpg on the way, 41mpg on the way back with the van. So probably nearer 30mpg on normal going.
