The Gumball isn't really a race, you have to kinda view it as a cross country cruise on land. Entry fees for 2012 are close to $30,000 dollars and every addition person (in vehicle) is about $5,000. This is based off of current Euro exchange rates with the US dollar but remember, everything but gas is paid for... lodging, drinks, food, impound fees, bail, speeding tickets and court appearances
