So i just bought the los santos custom property as franklin and its allows me to get free upgrades on my car which is awesome but I drove in there as Michael and they charged me which sucks there doesnt seem to be another one to buy as him is there a way that i can get free upgrades across all characters?
theoretically you should be able to pimp out a car as franklin then bring one of the others over to where he is and give him the car that way, maybe you'll have to switch between them frequently to keep frank from wandering off to do other things
everytime i think i've seen it all... someone does something stupider
Upgrade one, then drive it. Switch to another character and go to where they are and you'll be able to hang out with them. Get into the custom car and go hang out. When you return them you'll have two of that exact car (upgrades and all). Get into one and switch to the other character and get into the other. Have both of them drive to their garage and leave it. Quick save.
Here's how I did it.
Got adder upgraded and custom paint as Franklin. Get in and drive to a location I know well. Switch to Michael and drive to where Franklin is. Franklin wants to hang out so I drive Franklin's adder as Michael. I return Franklin after hanging out. Have Michael take one adder and Franklin gets the other. Drive to garage as Franklin and leave the car. Drive to garage as Michael and leave the car. Quick save. Now both Michael and Franklin have an upgraded adder.
So what does this mean? Later on, upgrade the cars for free with Franklin and then use this trick to give the other characters an upgraded car.
