Unmodified but low rear suspension

[oTVKo]

Hi all, New to the forum.

I picked up a Corsa B a few days ago. Rear seems low, apparently it is unmodified. I picked up the car crazy cheap so wasn't expecting perfection but just wondering what I should look at. Car feels fine, drives nice etc. I was told having passengers in the back causes rubbing? I haven't attempted this yet. Any advice and information welcome. People experienced similar? I will have a look underneath tomorrow.

Thanks.

Could you post a picture of the rear height
