I always say NOS (and pronounce it naws, not the correct N O S), but that's because when I refer to it, I'm always making fun of it. I do, also jokingly, refer to the turbo boost as NOS occasionally. =P

I started out which the Chaser. Apparently, It's the, or one of the, best starting cars, but I had no idea. I just like Chasers.
On the subject of paint, how are you guys managing to crank out such great looking jobs? I just can't get that kind of precision with the analog stick. Is it possible to hook up a USB mouse or something?
