Move the truck in the road. Follow the truck until you are blocked in. Shoot off the front bumper with the M-16 then continue to shoot it towards the vehicle. As it bounces off of the truck, the truck will get back out of the way. By doing this, you do not have to go off the annoying jump around back of the building that always flips your car over. When you catch up to the truck, get alongside him and just push the front of the it toward the lamp posts. He will immediately come to a violent stop. This will give you a perfect opportunity to kill him without totaling his vehicle, and thereby ruining the mission. To find the place where the car is located, continue on the path he was taking then take a left to get to the end of the map and make a right. You will see a couple of gunman on the right in front of the entrance. Never go in the other side, placing the target in the line of fire.
