So here's what have been working for SWIM on XB1:

Invite only session Fill up a 10 car garage with faggios Go with MOC to La Puerta parking spot Go with your sultan RS into moc Get inside sultan RS inside the moc, drive out and back in again Get inside sultan RS bring your phone, hit internet and right after a flick/quick tap on rt You should spawn on foot outside moc (if you spawn with your car outside, just go back inside the moc and try again) Go inside moc. Here two things should happen: you see two cars, sometimes one on top of each other or you see only one (try repeating the previous step) If you see one car inside another, just touch any with your character and then leave MOC Register your motorcycle club and call your faggio Go to the moc, accept the transfer car message. You should appear inside the MOC with a faggio and a sultan RS. Enter the sultan, drive out of moc and drive back again (this is your dupe, if you notice it will change to the faggio plate) Then from here you can repeat the internet explorer step and dupe another. If you get the timing right you can fill up a 10 car garage in less than 10 minutes so I've heard.
