Easy way to get the Jacked medal to platinum is to sit outside your apartment/house/garage and steal every car parked at a stoplight until you get a wanted level and then run into your garage, the wanted level should start flashing if you're fast enough, then just wait until the wanted level is gone. You don't even need to actually drive away, just get in the car then get out and move to the next one. Its seemed to work for me pretty well so far, just might take forever depending on how many are needed for platinum. 100 for silver so it could be a lot, but if you want all platinum medals then this would be the way to do this one I think.
