I remember thinking that wasn't a bad car...

This is why I'd never sell a hotted up car to anybody under 25 I'd feel guilty about it.

Many kids should drive hyundai excels with blocked exhausts until they are 25 at least

As a teenager, knowing what's right and wrong doesn't help. I've been there. I think driver training should also involve the pain the insurance companies and the police put you through if you have an accident. Not to mention the harassment from your friends and family are also likely to deal out to you.
