I cannon not record so I have a written tut. I do not believe I am the founder of this I seen a video similar.

Step 1 : Start up GTA V online, when you spawn sign out of your XBL profile.

Step 2 : when the game starts loading story mode sign back into your account.

Step 3 : Wait a couple of seconds in the cutscene and then press start and join an invite only session on your own.

Step 4 : Drive to LSC and park your car in front of LSC, then steal a random car and drive into LSC

Step 5 : Press on sell and then press A again but do NOT sell it, just wait on the confirmation to sell it.

Step 6 : Press start and press Lb + A + A and then press b once the game store loads up. You should still be in LSC in the car.

Step 7 : Repeat step 6 if done correctly you should spawn outside LSC in your Adder or car of choice. NOT the car you stole.

Step 8 : Drive your car of choice into LSC and sell it, straight after it says "sold" press start go to the online tab and press swap character once this loads choose the character you are using.

Step 9 : You should spawn outside your apartment in the car you just sold or if you are lucky round the back of LSC, you should then repeat Step 4.

Step 10 : Once you have another stolen vehicle in LSC you should only have to repeat Step 5/6 once then again you will spawn outside in your car and you can sell it again using the method in step 8.

Basically just keep repeating this and make a ton of cash, note it will put you in public matches this does not matter.
