Current Austin MYLR config

[PezAtl]

So I was hoping to hold off until December, but situation looks like I may need to purchase a car sooner than later.
What does a current new build MYLR out of Austin look like?

Model of batteries
Interior (new door card vs old)
Matrix lights vs LED
HW4
Anything else to keep an eye out for or suggest?

Also, can I refer myself?

Thanks in advance. I assume as long as it’s a current build, on the ground inventory will look the same. I’m in atlanta so all we get is Texas builds.

Thanks to those in the know!
