It is the first bonus car in the game and is unlocked by winning the 1 star Avalanche track in Wreckin' Racing. After you do so, you can buy it. Both versions have about the same attributes: durable armour, but everything else worse. Still, the upgraded Raw Van has medium attributes with its strong defence, so it is quite good.
Raw Van is also one of the playable cars in the DD Raw demo.
Raw Van resembles the 1958 Volkswagen Type 2.
