Nothing, if you can handle the associated costs.

I expect it stands out from the crowd and you will be driving your friends rather than in their hands.

It is a safe vehicle. I'm not 19 and I expect you haven't been driving for that long. I still don't feel comfortable in a car, certainly not a small car, on the most of the roads here--too much traffic and if you aren't going 10 over there is good chance you will get run over. I saw 4 elderly folks going 55 in a 70 zone in a Prius--I watched the news that night fully expecting them to be the latest fatalities. The Xs I have seen hit won the battle of the bumpers.
