Thought I would post about my findings yesterday.
Recently sold my Mk2 Focus estate for a Mk4 Mondeo estate.
The surprised arrived yesterday when I went to throw my bike in the boot. In the focus it was easy, seats down and throw bike in front wheel first no problem. So to my surprise when I tried to do this in the Mondeo it wouldn’t go in front wheel first. Unfortunately the Mondeo’s boot despite being bigger (longer and wider) it is not as tall especially at the opening as the Focus. I ended up putting the bike in backwards but the front wheel then blocks access to the boot.
So in conclusion if all you want is a car for transporting bikes strangely the MkII Focus despite being smaller seems to be the better vehicle. I don’t know about the Mk3 Focus but I imagine that is smaller and tighter than still.
