I don't have specific updated information on the last 5 VINs. When I was buying a couple weeks ago, I was shown some pictures of cars (which I presume were Photoshopped) in the special colors. I wasn't willing to pay the extra high price, so I didn't pursue the matter further. The "red" was actually a cool copper-ish color.
On the custom orders, I have to quote from the movie Dave:
Duane: I can't say.
Dave: You mean, you don't know, or "you can't say"?
Duane: I can't say.
There was a time in May when custom ordering was closed, but it's supposedly open again. From what I know, this was not intentional on Tesla's part.
I would suggest calling up a Tesla salesperson right away and ask if you can place a custom order now. If I'm right and you can, see if the configuration you want is order-able. It may not be. They'll probably have to get back to you on that. If you've already placed an order for a spec vehicle but haven't taken possession, I would ask to have them switch you at no penalty, assuming what you want is still available. If you've recently taken delivery, I would ask if they would take back your car to use as a test driver, and order you the car you really want. Or, perhaps some other suitable compensation.
For anyone who's considering a Roadster and wants it just the way they want it, time to pull the money out of the mattress.
