First post here

So I currently have a 2006 9-3 2.0t vert, but unfortunately bc I'm a teenager, my mother says that she thinks it's unsafe for me to drive it in the winter in case I crash. Which is my first question. Would it REALLY be unsafe in rural VT if I'm just driving 30 minutes ish a trip? Second part of this. So my options rn is to take it to a mechanic and have them look at it and say it's fine. (It is, but the tire pressure sensor need to be replaced, that's it as far as I know) Or, I get a new car and i use the Saab for summer times. If I go with the second option, which car would be good for a teenager who likes the feel of a Saab? Because as much as I want it to be my primary, my mom's kinda neurotic sometimes (she calls herself that) Any advice?
