I've borrowed a friend's Honda Fit to haul pins multiple times and it works great. Works nicely when you can move the passenger seat all the way forward and angle the pin so it goes from the back left to the front right for additional space. In other words, no need to move the driver's seat forward -- I had it most of the way back, exactly where I wanted it. Obviously, it's a different story if you have a passenger, and that's the only real drawback.
My friend's Fit is a 2012 model. I've heard that this latest design has a taller opening than the first generation ones.
