You know how you really want a helicopter but it takes so long to get agility 5, well I have a solution.

The requirements are simple, you need driving 4, strength 5 and thats it. So first you have to face the wall on the right of the Agency Tower in the SUV and drive the SUV into the wall.

When your'e about to ride on the wall hold down B and keep holding the gas button and when you're up there you got to look at the building that is closest to the helipad and throw the SUV on top of it.

Then with the wires next to you jump on them and then on the window seal get on top of the building.

Then get as far back as you can then drive the SUV while holding B and just as you are about to fall off let go of B and then you will land on the pad.
