The Honda Fit. Amazing little car. I don't have one but the wife works at a Honda dealer and the stuff they get in that car amazes me. I actually want one, a manual, which I think would be an awesome city runabout.
She actually drives a Subaru Forester (the pinnacle of utility SUV's IMHO) and my bikes fit in the trunk/boot/hatch with the front wheel off.
If that isn't around I throw (gently) bikes in the box of my truck. Which obviously fits a lot more than that.
