This a motor vehicle used to take part in the Mystery box Rally.

The term arises from the fact that participants sign up to take part in the Mystery box rally without knowing what car they will be using or where they are going.
The cars are of unknown quality, and are usually secondhand cars that have been pulled out of the Manheim Auction System at random, and their value could be anywhere between $100 and $10,000.

The Mystery Box rally is a spin off of the Shitbox rally, and also raises money for the Cancer Council.

A motor vehicle of poor quality, that is valued at or bellow $1000 and is driven on the annual "Shitbox Rally" through extremely remote and isolated areas of the Australian outback. The idea being that each team, of which there are 250, needs to find a Shitbox and prepare it for the Shitbox rally without spending more than $1000 on it.
Teams are also required to raise money for the Cancer Council. Since its inception in 2010, the Shitbox rally has grown to become the single largest fund raising event for the Cancer Council. The rally now raises in excess of $1,000,000 annually for the Cancer Council.
The people that take part in the Shitbox rally often refer to themselves as "Shitboxers".
Teams travel to Australia from all over the world to take part in the Shitbox Rally.
If your Shitbox dies on the rally, it is going in a hole... and your rally is over!
