Which version mondeo? I did 4 and 4 in my mk2 hatchback all the time. Just needs the wheels off. Here’s how:
Wheels off, load biggest bike first. Single seat in the back folded down.
First frame in across the boot flat, front of the bike to the right, mech in bottom left corner as you look into the boot. Bottom pedal fits in the hole at the near side of the boot, just push past the carpet. So it sits completely flat.
Next three go in facing alternate directions. Put 2 wheels on top. This should have your boot filled to the level of the top of the seats if you’ve done it well, plenty space for bags. Remaining 6 wheels go vertically in the space where the seat is folded down. Bungee round the grab handle in the roof holds them in place.
Easy.
