Per towbar fitting: before I retired one of my colleagues - also a caravanner - had one of these as a Co car and he said it towed superbly. However there is an issue with rear lights - if those on the car shown are the same.
The rear lights are on the tailgate. When the tailgate is opened the lights shine up into the sky, so in their wisdom Vauxhall fitted a second pair of rear lights on the part of the body that is exposed when the tailgate is opened. Good idea - except that they also fitted auto-switching so that the on-body lights only come on when the tailgate is opened (logical) but in the same process the lights on the tailgate go off. Unfortunately the caravan tail lights are usually operated from the tailgate circuit so they go off as well!
Ergo, when you get the towbar fitted investigate this switching action with the fitting company, and in particular make sure that the caravan tail lights stay on when the car tailgate is opened.
Good luck!
