Welcome to the site! I was just a bit younger than you when I first got into this stuff, no I'm SO MUCH OLDER (19,
). Good to see you taking initiative though.
If it were me I would do the best with what I had while trying to save a dollar a day from lunch money or eating pizza on the weekends until that + selling the current car could get me a little civic, crx, or metro. Keep your ear to the ground, because every so often they go for almost nothing.
Welcome aboard.
