This is the hardest side mission of GTA III, but don't be discouraged, the hardest part is at the start, which means the player can replay it quicker should they fail. If the car is intact after a failed attempt, just park it near the start, get out, and get in, the mission will restart. Drive to a small hill in the south for first checkpoint. Return to the start, approach the second checkpoint from north, if the player tries to climb the cliff from first checkpoint, the mission will be failed. Go north, pick up the eighth along the road, don't let Colombians bust Claude.
