can't by it on GT4, gotta win, so far as i have found.
then win it! I remember getting it early on in the game(think you have to beat all the rallies to get it? I can't remember) and it would go over 1000 mph popping a wheelie. I can't remember what I used before I got it though.
yep, the only problem is that on GT4, if you hit the wall, you get penalized for 5 seconds, 1,800 is a handful on a tight course. the hyundia accent does pretty good, but i still can not beat the special stages section
