Remembered that for GTR2 someone created a car selector with which you could build up the grid to your own liking. A very helpful tool for Singleplayer Races.Don't know what S3 has planned for the future (and if I remember right with AC you can assign each car and group the way you want to, right ?) so specially for dedicated Servers (MP) it would be a great help (consider Multiclass Events alone - also when organizing them) if you could assign/restrict cars and classes freely.
hm, for dedicated servers it is already possible if I get it right. You can select a hole class and add single cars from other classes or you can select only single cars out of different classes... A similar feature is missing for Single Player but there is Multiclass missing, too. Or do you mean it down to livery-selection?
Yes specially to limit cars/classes available for Multiclass Races (you know everyone wants to play with the most shiny toys but not if his access is restricted to a certain amount of cars/classes/liveries )and as Dedi doesn't work for me (can't join own server) I didn't look much into....
