Hi, we had a 2litre pinin GDI petrol towing a 5 berth sterling europa. the car itself was quite a good tug with a surprising amount of power Be aware that there is very little room in the rear, the rear wheel mounted on the tailgate made
hitching "awkward", the fuel tank was quite small (lots of stops) and it was very thirsty, even when not towing! it also didnt like reversing with a van on the back and was very low to the ground when towing over speedbumps/ramps. It wouldnt be my first choice.
