I have an Idea, but dont sure if this is the place apropiated to put it,
well, there goes:
I Think we can change the way to manage the cars we have to one similar to the rpg games, i mean, what if you begin with the smaller car (UF1 for example) and with the credits you earn for winning races you buy things to improve it, or other cars or something, you know, something similar to the NFS IV. Doing this you'll have your own cars, different frome the rest. I think it would be also a good idea to divide the cars in different groups (GTRs Formulas etc), and after in the servers, instead of limiting the cars you will limit the class.
PD: sorry for my english, i'm spanish xD
