This is totally mad. Man enters a $500 1991 BMW 318i (rear wheel drive, obv), found on Craigslist, in the Mexico round of the 2010 World Rally Championships.
A choice highlight:
Some kids threw boulders in the road on a transit and I punctured my gas tank losing nearly a half tank in 24 km on the next stage. Best part, the officials pointed out our leak and showed a handful of gas to us when we asked how big it was — I knew we were screwed, but they said we could start the stage so we did. I patched it with just stuff in the trunk — RTV and balls of duct tape
