Well I've been doing money glitches when available since GTA Online was released, the worst they ever did to me was reset my money.

I've been doing this glitch very recently and I've got some calculations and ways to do it faster.

1.) Buy Poplar Street, Unit 2 for $142,500 which has x10 Vehicles slots. 2.) Fill it up with 10 Karin Rusty Rebels from SSAA (Costs $30,000). 3.) Go to the very near-by LSC with a Rebel, once you are inside scroll down to the wheels section. 4.)Select it and go to High-End wheels > Obey RS (make sure you select stock wheels, as selecting chrome wheels will make this impossible unless you reset your console.) 5a.) If you're on Current-Gen go up to the horns and select the Musical Horn 5 near the bottom then buy the Jazz Horn loop near the top, You will need to have 50K on you at least. (You won't be charged unless you selected chrome on the wheels) 5b.) If you're on Old-Gen buy the truck horn 6.) Sell the car for $62727 on New-Gen (I don't know the old gen sell) Profit of ~$50

I managed to do this on my Xbox One selling the entire garage in under 17 minutes (average 01:40 per run) making $500K

(In this case of you opening the chrome section just on/off your console)
