In Rocket League, adding new items and cars to your inventory can cost money. The in-game currency is a credit, and each credit is worth $.01. That means, if you spent 24,500 credits on a battle-car, you’d be spending $245 in real cash. And that was the price of the Titanium White Dominus at one point. Prices for rare cars and items will fluctuate, even between platforms, but this Dominus variant has consistently remained the most expensive battle-car.
