Base vs Founders

[Prowler]

I'm quite sure that Elon has mentioned on twitter that the Founders Series Roadsters will come with the SpaceX package but I wasn't able to find the tweet. I was able to find the thread where he talks about the package in general, however.

He was talking about a 2020 edition not the 2025 edition.
"Is the Spacex package included on founders series? Fingers crossed for my founders 2020 roadster to include it!"

It sounds like the SpacEx package will be an additional option. The question is, How much? Knowing Elon, you’ll be required to provide
proof you are actually insane to use it!

I realise this is an old thread, but....
I think the cold gas thrusters are a significant part of the SpaceX package. And my understanding is that the compressed air tank (and multi-stage compressors, presumably) will replace the back seats. So it's a choice of "SpaceX" or "back seats".
I'd be very surprised if no Founder's Edition models will have back seats, especially given that they will be reviewed by by jouurnalists and others worldwide.
