Contracts are pink dots on your map and in the GPS they are pink blips. To do one of these quickly I would advise you use a large vehicle like an SUV or a Van (the truck is to slow). After you have found on of these vehicles go find a pink blip/dot. When one is found start it up, and then when it says go you have to take out a target car within a certian time limit. The vehicle your have to chase are bullet proof and have a tough outer shell so the best thing to do is Melee attack them from the side and into a wall. Do this in under a minute and you will receive and S rank.
