i think it's a stupid idea. but it's your money and you should do whatever makes you happy. too much negativity on this board. who cares if you're a dumb 16 year old who wants to rice his car. i got my wagon for a reason and you got yours for.... well, you have your reasons.
i will say that i spent thousands upon thousands of dollars on paintball in high school and i sure could have used that money during undergraduate, grad school or even now to put a down payment on a house. remember, it's just a car. no point having a fancy car only for it to take you to and from work/school.
