450 is still a lot though. I don't know how much my dad makes but I'm pretty sure he is well enough above average (haven't investigated what "average" is, but at least a couple thousand a week) that if I were an only child, he'd just walk right out and bring a car home. Not that I'm saying I want to be an only child of course.
At the school where I'm enrolled part-time, I've seen two 370Zs, two AMG Mercedes (E 55 and CLS 55), Dodge SRT models, a Mercedes SL 500 (definitely was a kid driving that), heavily modded GTOs, Mustangs, Camaros, and 4x4 pickups (mostly older Ford's or Rams). I can't always tell when cars are being driven by kids or teachers, but the teachers lot is very well defined and the most interesting car I've ever seen in there is driven by my ex-trig teacher (a white Lexus).
