The Rebla GTS is Ubermacht's luxury SUV, and this GTA 6 version appears to draw on the fourth generation BMW X5. It has not shown up in official trailer footage. Everything we have comes from leaked material, so treat it as unconfirmed rather than a sure thing. The Rebla name has appeared in the series before, which makes a return believable, but nothing here is settled until Rockstar shows it.
The Rebla GTS has only been seen in leaked material, not in any official reveal, so its presence in GTA 6 is unconfirmed. That also means we cannot say how you would acquire one, since there are no confirmed details to work from.
If it follows the pattern of past Ubermacht SUVs, expect a purchasable luxury option once the game is out. We will update this entry the moment Rockstar confirms anything officially.
