Theres a website that just put the AutoArt models for the twins up called Massdrop. They lower the price based on how many people buy an item. I just put myself in, so I'm hoping more people buy a model as well so our price goes down and we save a few bucks.
Here is a drop link direct to the models:
http://dro.ps/b/0efijes , or you can go to their homepage
www.massdrop.com and you'll find them in there.
I have an FR-S in Halo white, which isn't an option, but they have the 86 in Halo white, so I'm getting that one.
