as a warning, the carpets and trim on zafira's are Awful! they suck up all the dirt and dont like to let it go! close to a form of fluffy cardboard, i know many guys i met through valeting that pass jobs on to other guys due to them being zafira's,
the back seats are not particularly comfortable either and the material is not nice for long journeys (mother hired one to transport her, step dad, me the wife and littlun on a trip a while back) but for what they do they are popular, recently done the same trip in a Ford s-max and have to say was like night and day from the Zafira, (equal levels of trim etc.)
of the two i'd prolly look at the pug, not quite so big on space but i'd say prolly better on comfort!
