So I was playing, wondering around and one of those random events happened. Some guy stole some other guys motorcycle. I kill the guy and bring it back to him and a few hours later i get an e-mail from the guy saying hes the owner of The Ark pet store or something and gives me $100,000 worth of shares in the company. When I went to check the price on the market it pretty much doubled so I got about $180,000 for returning some randoms bike
Also I bought a £250,000 car a while ago and took it on a mission. It's pretty much disappeared, hasn't been impounded and its not in my garage so that was a fine waste of money...
