Well, before making such an important decision, one must do some research, right? So the porn star's name is Julia Boin, and you can do a google video search for "Chinese porn star Julia Boin" to find her body of work (pun intended). Then after watching her in action, you can judge responsibly whether or not a night with her would be worth giving up a Porsche. Strictly in the name of scientific research, of course. Julia does have interesting boobies...
