wow many replies.
It sounds on the most of you that custom cars would destroy the whole game. I mean if you dont like a custom car why download it ? In my case, modding is an oportunity to get my models in a game.
And it is not impossible to make servers restrict custom models. If you dont want to race with custom models, just connect to a restricted server.
I think modding is something that makes a game last longer AND gives people like me a chance to polish their modelling skills and actually be able to test their own things inside a game-engine.
