There is plenty of space under the floor behind the back seat. The space is car-width, about 10 inches deep, maybe a bit more and half the boot floor deep. Plenty of room for me which includes three hats, accident gear, cable bag, tow rope, shopping bags, and still room to spare. No spare wheel as it has run-flat tyres. Big enough for all your knick nacks, like first aid kit, coffee holders, a few rags, towels as well as the stuff I mentioned earlier. GREAT car.
