Arenawar

Arena War is a business featured in Grand Theft Auto Online as part of the Arena War update, which allows the player to buy an Arena Workshop, as well as upgradeable and battle-ready vehicles from their website arenawar.tv

Description
Arena War is a business that allows the player to purchase a dedicated workshop for storage of battle arena vehicles.

They also sell various stock vehicles from other websites for unique upgrades, as well as custom battle vehicles, separated into three main categories, ranging from custom off-road vehicles to even light tanks.

Workshop
The player is able to purchase an Arena Workshop, where all stock and Arena-ready vehicles are stored. One can choose different styles for their office and workshop graphics and colors. They can also add two garage floors, each one able to hold ten cars and decorated in the same way as the workshop, and hire three different mechanics to cover the modification types the vehicles need.

As expected, living quarters are also available for this workshop, for easier accessibility.

Upgradeable
"These vehicles are only an upgrade away from being Arena-ready. Purchase a stock model, take it to your Arena Workshop, and get your mechanic to upgrade it to any one of the three Arena styles."

- Description.

There are seven upgradeable vehicles, which are also available on other websites. However, workshop owners have access to trade prices after reaching a required Arena War Career level, which is discounted by 25% from their base prices.

Arena-ready
There are a total of 15 vehicles already modified for use in the arena, categorized into the same three types as those available from the upgradeable vehicles.
