Hey heres an easy way to get lots of cash in the insurance fraud missions. First get a police car (any civic vehicle will do but police cars go faster) then activate the mission. Now as you speed along towards the scoring zone be ready. When you are in the scoring zone have a head on collision with another car or just crash into a wall. You should go through the winscreen getting you 5X ejection a 2 to 4X civic vehicle and also a 2X air. I've found this is the easiest way to pass the missions just by doing this over and over again. my record is $307,673 in just one crash. It' s very useful to keep the police car to so activate the rapair car cheat if you want to keep the same car or if you dont want to cheact try to find a new cop car every so often.
