Hatchbacks with the seats down will fit a ton. I can get a 4u head, 2 Schroeder cabs, pedal train hard case, bass, backpack, all that in my car, and still have room for another guitar and backpack and a passenger.
I also could fit all that in a mustang. If the back seats fold down you can tertis it in easy.
