How can I get one of these in PC single-player mode? I’ve heard that they just spawn in players’ garages in the console versions, but in the PC version, the only way to get an Osiris seems to be to purchase it for $1.9 million from luxurymotorsports.net. This is a problem, because despite my best efforts to complete missions, rob armored trucks, and play the stock market, my richest character only has about $200K. Any pointers?
