You have to do a lot of drifting on that track. I would recommend a kart, as opposed to a bike, because you get more time to drift then time to willie. Heavy Characters have more speed then lighter characters. I would recommend a heavy person in the Honeycoupe or the Flame Flyer, or even a medium character in the Wild wing.
Yes, you get the manual, and the case. When I bought Pokemon Heartgold, I even got the pokewalker sent to me!! Don't be afraid to but games from here. Sometimes, you can get games cheeper from here then stores
Maybe it got a little misplaced in the mail. I once had to wait eight days to get a game in the mail, and it was the wrong game!! Patience is probably the best thing to have right now.
P.S. when you get that game, can you tell me if it's good? I was thinking about renting it.
