2003 forum post states North American Sega GT microsite was not fully implemented

Heres a little quote from the back of the game

"Upload scores and lap times to the internet or trade your racing machines using the VMU"

that would have made things a bit easier if they actually did that. I got the game like half a year after it came out [that would make it Jan-March 2001 as the US release was Aug 2000] and when you'd go to the download ghost data on the site it said "coming soon" the sites down now anyways......
