Which car as a beginner?

Hi love community I’m new here I wanted to ask how much PS you’ll find too much for a novice driver. I became on 10 February 18 and wanted to know what you think of the Ford Focus ST170. Because I have to get this first car, but I’m thinking if that’s not too much ps since the ST170 already has 170 ps as the name says it’s just my parents think it’s too fast. What do you think of 170 ps are enormous and unmanageable just like my parents my or are it just a lot where you can say ok 170 ps is fast but not exaggerated. Thank you for the answers LG Andi
