I'm a highschooler...then only reason I have any money to spend on my car is because i work my ass off. I payed for more than half of my car, as my parents weren't willing to pay much, I pay insurance, and I buy my own gas. Because I've been working a lot of hours this summer I'm building up more and more credit at work (I work at a car shop) and use it to fund any mods I want.
