If you need to make quick money like 1000 0r aboveI didhers what to do. Just get a car like a truck a belly or a bus and drive up to the junkyard at the very top of the map and drive the truck in the black and yellow square and exit the car and walk out of the black and yellow square. The car will be crushed and you will get about 2 or 3 thousand dollers. You can keep doing this untill you have as much money as you need.
