17 with 10k in savings

So I recently hit 10k in savings after about 2 years working at my job. Recently i’ve been promoted to a server and 2k of that was made in just a month as i take home about $2400 and pocket into savings about $2000 of it. Should I invest into something? Keep saving? maybe even a certificate of deposit? I was thinking about buying a car maybe however i already have one and it gets me from point A to B no issues however it’s nothing too nice and i wouldn’t mind having something a bit nicer. August of next year I will start community college so maybe I should keep saving for textbooks and tuition? What should I do?
