Do you guys know any good websites to buy a blue Skyline? Thanks! ;D
I don’t know where, or if they have them in stock, but I can name a few:
I’ll think of a few later, but your best bet is YoYoNation.Com. 
If you are only specifically looking for a blue Skyline, you’ll probably have a relatively hard time finding one, but you can try your luck out of BST forums. As for other Skylines, there are a few still in stock at YoYoNation.
Yep! 
Or, you can try to satin/re-paint it - if you’re a modder.
I would not reccommend this, but you can do it. No going back.
If you work at a metal company, you can re-annodize it.
