Car Builder
Put a vehicle together the way you want it: pick one of the 21 vehicles, a livery and a cosmetic for each slot, and turn it around in 3D. Everything is unlocked here; under the view the list says what unlocks each piece in the game: the challenge trail, the crate, the item recovery or the Mechanic.
Arrow keys turn the view, plus and minus zoom, 0 resets it. In the cosmetics lists the arrow keys move between cosmetics.The models, liveries and 138 cosmetics are the game's own, placed where the game mounts them on each vehicle. A copied link opens the same build.
