Well my Mondeo fits 2 kids, 1 wife, their baggage, my twinset + the rest and tows a large Rhib quite well, but its an 1800 petrol.
Make sure its a rear wheel drive, mine is front wheel and really don't like getting a Rhib up the slipway at Dover, my mate has a Mondeo estate, which has even more space and being Rear wheel drive, gets the Rhib out when mine fails.
