YuRiPaSo, probably the one you get with your PS2 if you buy a GT4 pack, you have 123 secs headstart, and if you buy it without a new PS2 you'll get 115 secs headstart. I had the 115 secs headstart, and won this one with 0.3 secs. Cost me all afternoon though. But now I know the track well, so that's good. I'll try it some more time, look if I can win by 8 secs, that should be possible.
haha, maybe they wanted to be nice to the ones that buyed the GT4/PS2 pack, but screwed it up.
