Here's a money glitch for GTA V that works after 1.09 Grab a vehicle make sure its worth as much money as possible Head to the Los Santos Customs near the centre of the map Park close to the LSC and then jump out and start shooting stuff up. When the police arrive, keep shooting until you get killed. This will cause your vehicle to be impounded. When you respawn call your Mechanic and request that another vehicle be delivered. Note : This next step needs to be done as fast as your greedy little fingers will allow! As soon as you make the request press Select (PS3) or Back (Xbox 360) and then press up five times only, this should let you select “Request Personal Vehicle” again almost instantly If done correctly your last vehicle will be delivered to you and the one in the impound lot will be destroyed. Now call Mors Mutual Insurance and the same vehicle will also be replaced in your garage. Drive the vehicle your Mechanic bought to your garage and replace a crappy car. Now get in the car that MM Insurance sent, go to Los Santos Customs and sell it. Finally, request that your Mechanic bring the other car back (the one that is uninsured/he delivered to you already), and get it fully insured at LSC. Rinse and Repeat...
Read the comments on the video is only a way to get some money back on cars u bought before the 1.09 update.
There is a work around to still sell super cars. Setting spawn location last. Get in a car that can be sold and have the car that you want to sel near the lsc. Drive the car you ddont want to sell in it press sell 2x leave it there and go to xbox gamestore while stil in lsc. Then u unplug internetcable, put it back up u go to spl then, start a invite only session, from there u spawn near lsc with te car u can sell. If not clear use google please. The amaunt of a not full adder is 200k for me.
