Nice idea, I remember something suggestion before by mooman.
Currently we save about 30 (guess) united of data per player, but with this suggestion it would increase the data stored by about 500 (guess), I'm a bit scared on how that will be handled by SQL.
30 ( player stats )
211 (vehicles) x 2 (colours) + 211 (rims)
663 units of data to store, per player. To be honest with you all, I don't know enough about SQL so it might possible and we won't notice any lag.
What do mooman and pod think?
