Mondeos are big, but counterintuitively the boot of the saloon is harder to make use of than the hatch- big capacity, smaller entrance.
Mine is an estate, and superb bike hauler, but it’s a big ol car and a pain to live with sometimes (frinstance, if I go to my local tesco it physically won’t fit in the parking spaces!) But it’s well nailed together, a reasonably nice place to be, and you need a sherpa guide to get from one end of the boot to the other. Mine is a ghia-x so execu-barge and surprisingly all the toys still work at 120000 miles- it’s creaky and rattly but it’s in good shape overall.
I reckon estates make a lot more sense for bike hauling duties though… Focuses tend to cost a wee bit more but the focus estate, especially the mk1 and 1.5, are fab- ridiculously big in the back, and none of the penalty of gigantitude that the mondeo has.
