Why does my Audi A3 vibrate at high speeds?

I recently purchased a used Audi A3 and have noticed that it vibrates at high speeds on the highway. This is my first time owning an Audi and I'm not sure if this is normal or if I should get it checked out. Can anyone provide some insight on what could be causing this?

It is not normal for your Audi A3 to vibrate at high speeds. This could be caused by a number of issues, such as worn tires or unbalanced wheels. I recommend taking your car to a certified mechanic to get it checked out. This will ensure that your car is safe to drive and prevent any potential further damage.
