It's solid. I was in the Commodore RS which is a 2.0-litre, four cylinder petrol engine, so you're not getting the full V6 experience (though there are V6s in the range, seek them out if that's what you're after). But for family driving on the suburban route from home to work and school and daycare and round to sporting activities, the four cylinders were all I needed.
I found the steering slightly stiff but nothing major, and the handling was good. It has enough power to get up hills quickly and I didn't feel as though I was lacking in the speed department. It took corners well and I felt confident driving it. All in all, a good drive.
Parking was fine thanks to the reverse parking camera and rear collision warnings, but the turning circle was quite large, which is always a hassle when you're doing lots of turns to try and find a park for school pick-up.
It's lower than an SUV obviously, so you don't have that high vantage point on the road, but I'm used to that and it just depends on your personal preference.
