I didn’t know the previous GLA had a 360 camera – the current generation does not, no spec and not optional, sadly.
In regards to 360 camera, there’s three options from the top of my head. The Peugeot 3008 (the 225hp PHEV in top spec, GT Premium or something it’s called), the Seat Ateca Xperience Lux (we have the 2019 model of that car), and the Tiguan Elegance – but for the Elegance, you’d need to pay extra for that option. I just mention it because the Elegance with 360 camera is still reasonably priced in my opinion (£2000 AP, £735 the area view camera – panoramic sunroof, matrix LED etc all baked into the spec).
I’m pretty sure the Hyundai Tucson Ultimate has a 360 camera too, but i’m not 100% sure on that.
No idea in regards to hatchbacks, coupes etc – due to my wifes disability we have to drive something with a high seating position, so that’s what i read up upon.
