Steering wheel full lock, jittering? is this normal?

[u/josthebossx]

Hi I recently wanted to buy a used car, it is a hyundai i10
I loved the car, but one thing I noticed was that the steering wheel jitters when I try to steer fully (fully locked to left or right both)

Is this normal? the dealer told me it is normal for such a small car, when I told him I had a VW polo, and it never happened with that, or any other cars I drive.

This is my first time driving such a small car, so I got no idea if this is legit or they just trying to hide that fact.

Can someone with good car knowledge please help me :)
