Money Situations

Now that I have just been getting into import cars, and modifying them and such, I have grown accustome to the money situation I am in. I get a little thrown off when I see a kid my age driving the same model car, only souped up to hell. I wanna know where all that money comes from. I have a job and all, but big paying jobs around here dont hire till your 18. What do you guys do for money? I mean some cars with $18,000 dollars invested or more, and some kids are no older then 17 and doing that? I hate not being rich man. lol. So again my question is what do you guys do for money? Besides the occasional nickle bag sale. (dont look at me that way I know someone on hondastyle does.)
