If you are from Liverpool in UK (the boot as opposed to a trunk, is a give away!) just to clarify a mini-van is a people carrier, not some transit van!!! My sister-in-law in Milton Keynes gets very upset when I call her car a mini-van, "it's a people carrier" she replies "not a van" White Van Man worry!!
We struggle with trunk/boat space in our cars, basically small suitcases are better than the large hardcase ones, we can only get one of those in our boot (an Audi A4) but there is room around it for smaller cases. We had to have a hire car one time when our car was in the garage, all they had was a towncar...now there's luggage space!! You could probably fit Mickey Mouse in their...though I wouldn't try it!
