Looking at the Astra's tapering roofline, you might expect rear space to be on the tight side. Surprisingly, rear head room is generous enough for tall adults to sit comfortably. Leg room is on a par with the larger Skoda Octavia, which is the biggest complement you could give a car in this class; for years the Czech car has been the best for rear space.
A wide cabin means shoulder room is good, too, although three adults abreast will still be a bit of a squeeze. Even so, you certainly won’t feel claustrophobic, thanks to big rear windows which let in plenty of light. Getting in is easy, too; the doors are bigger than the previous model’s and they open wide.
There are also reasonably sized door pockets, and you can get heated rear seats and USB ports back there.
