...and opened "Challenge II" in Wipeout XL (NTSC: US/CA) on PS1. Now, I'd like to know: What is gained after doing perfect in the Challenge II? I heard that you get 'Red Bull' afterwards. Is this an even harder race class?

PS: Here's my favourites from all Wipeouts:

Wipeout 1 (Saturn version) has nicest music.
Wipeout 2097/XL has nicest graphics & tracks.
Wipeout 3 just screams in replay value, as well as that nice lady voice! :-D
I don't have any others.
