after 20 years of Grand Prix 2 (buyed this game 1998) I found gp4, and with the game too many changes, I installed the game from gp4central site web and two mod 1993 and 2016. Progress is far-reaching, and when i search mod 2017 , and when I got into the urge to play this game again, I found few websites that talk about GP4. I sign up here to download the mod 2017 (Gp4 2017 Mod v0.9-rc.1) and I know it's not possible. I read a little in the forum (in a Spanish discussion I understand that now sells) on ebay you can buy mod 2017. I ask how I should do to get the mod2017 It's free ? do you have to buy?
