I have a cool skin idea, some delorean's had this "black stripe" paint job that came stock on some of them, I think that would be a good addition.
When its ready. Try not to ask about release dates, it tends to put pressure on the creators, and the community tends to shout at people who do ask about it.
that actually is a good idea, although Lucas said color and skin support will most likely no be supported in the final iterations
