Honda Fit.
I always remove the front wheel. A large frame 29 + fits but I have to move the pass. seat up some. Road bike is no problem. I keep several moving blankets in the back and can put one bike on top of another no problem. For distance travel with a passenger I remove the seat post and put the bike vertical with the rear tire between the seats and the fork locked into a holder. I can put 2 other bikes with the wheels off, leaning against the center bike. That leaves room for the wheels and luggage.
