At Repoman mission (78), you must steal 3 car, and bring them safety to garage. I have some hints, 1: NO COP! So you can shot, drive fast, crash, or whetever else without chasing by a cop. 2: After you steal the car, you will chase by some gang member, of course they have a weapon to shoot you, and the car, the hint is : Each car you steal have 1 gang car, that is white four doors sedan with two or three gang members inside and outside, Kill them first BEFORE you steal the car, Remember, no cops! After baam, boom, baam, they died, get the car to the garage in peace without any single bullets on it, do the same thing on the 2nd, and 3rd car. You will be more easier if you use a cheat, like all weapon, you just Boom them, and run. Simple huh?
When doing the job where you have to help the other car win I recommend using a sturdy car (negotiator works best), and going the opposite way on the track and crashing head on with the other cars. After a couple attempts all cars will be unable to move and the car will be able to have a guaranteed win.
Because when you steal a cop car you automatically have full felony (heat) on both the car and yourself, it can be hard to get one to your garage without dying. What I would recommend is to shoot at a civilian or kill them near a garage, and wait for the investigation cop car to come in. When it does, the cops will get out and start to examine the scene. When they do, get in their car and drive away from them until they lose you or you kill them, and when they lose you take the car to the nearby garage and clear it's felony. You can steal a S.W.A.T. Van in a similar manner.
On the mission where you have to hijack the columbian's car and rig it with a bomb use the car invincability cheat. The bomb will not explode so you can do what ever you need to win. Also it is usefull if they close the steel doors so if they do enable the cheat and take the way in you used to get there in the first place. Hope this helps
This is not much of a hint but I think it is cool. When you are driving anything press down on the directional button and you will go slo-mo. One hint for when you are in slo-mo it is hard to steer because the camera is facing the car on the side.
