I deadlifted an old Volkswagen Beetle about a year ago by the rear bumper(you can't do this with modern cars though, because the bumper isn't attached to the inner work, and you'll probably break it off). That was very doable, and I was deadlifting around 525 for a few at the time.
I guess anyone who can pull 400 can pull it off, as long as you got a very good grip, because it can't be confused with a barbell.
Tipping it is a little harder though. If I were to train for it, I'd put my money on tire flipping and rack pulls.
