From what I’ve heard from the FAQ spreadsheet and various other threads:
Battery pack – Cannot be changed after purchase.
Enhanced sound system – Not certain.
Offroad kit and AWD/2WD switching – Possibly but they aren’t sure yet – will have to see.
Solar hatch/hood – Possibly but not certain yet.
Camping pack/Safety pilot – Probably can add after purchase.
Dog kit – Almost certainly can get after purchase.
