Great game well worth buying,vehicles are great and a huge range of them,helicoptors that can use in plane or helicoptor mode. Gangs are tougher as well as police as they all deploy roadblocks once you have annoyed them. Good range of foes with special abilities, can go through all the missions quite quickly on easiest mode. However so much to do in game with activities,assassinations,chop shop as well as just doing your thing!! Only negative point seems to be that it doesn't save cheats unlike SR2 as well as no god mode full ammo etc. However with the upgrades available through your phone and friendly fire to upgrade weapons, really not needed except maybe at start, Radio stations not as good as previous ones but that's maybe personal preference.In short buy it and enjoy, fave vehicle is possibly the crusader tank ;-)
