I know you dont want to hear this cause i know i didnt at your age butttt,
dude seriously...for your first car, buy something cheap, slow, and easy to work on, and cheap parts, that way you have to work on it a lot and you will learn about how everything works and you will learn to respect it more, no joke. I bought my first car at 14 it's a 1967 VW Beetle and man it was a mess, but i worked on it till i was 16 and ready to drive and it was a very dependable car, and loads of fun, not to mention kept me out of trouble. Now i know old school VW's are way too expensive to restore now, (have spent $28,000 on mine in the last 8 years) but it runs 11's and is mint! i couldnt get rid of it, too many good memories. But in all seriousness start off small and work your way up. No sense getting a HiPerformance car as a first car and destroying it.
Point being, hunt down an E21 or an early E30 318 or 325e, or a watercooled MKII vw jetta, gti, golf, all awesome cars for bombing, learning to drive, and learning how things work and how to work on them. That teaches you patience, dicipline, confidence, and just plain mechanical smarts!
I dont reccomend a 2002 for a first car though, they are classics, those are what you buy for as your 3rd car
they are great cars but like old air cooled VW's expensive! unless you score a deal on a fully mechanically restored one for like $5k
granted mine is off the charts but you dont have to spend as much as i did.
Im not trying to be a dick im just looking out for you
too many of my friends in HS, back in the good ol days, destroyed their "Fast cars" but mine kept going
kept me out of trouble too, it sucked having the bomber, but now that i look back i wouldnt change it for the world
Edit: Wow i just realized i have owned 6 cars now
