First, you have to activate the Apartments Chop Shop list in Little Shanghai located in the Chinatown District.

Next, you must gain notoriety with The Brotherhood.

Stay in that same area.

Each gang car that comes to attack you will more than likely be a Swindle.

Kill the occupants and drive the Swindle into the chop shop.

You will get 1,000 for the first one and 500 for each one after that.

And don't worry about the Cops. Your notoriety with them disappears after you enter the chop shop.

Do this for as long as you please.
