Devs dont have capacity to add full customization like in forza.
Some paint jobs were announced in the last alfa stream.
For me it would be ok to have current body damage system, and to have a couple of options - old rusty look, wear look (like we have now), brand new look. It may be changed in campaign mode...one if the variant - buy old rusty cheap truck, repair it step by step, one of the steps (optional) - to repar and paint body.
And base colors - military, and civic (1or2 civic colors, EXISTED in rl).
