Went through this process myself, and was dead set on an S-Max. Looked at a few, and just couldn't bring myself to buy something with no spare wheel at all, not even a space saver – also thought my kids would destroy the interior of the S-Max. Eventually bought a new shape Hyundai Santa Fe with 7 seats.
Plus points:
Big, comfy, quiet, much better economy than my previous large petrol estate (only a 2.2 diesel, so low road tax compared to XC90 or Discovery), full size spare wheel, seats fold flat into floor, still has LW on the radio for the cricket, 5 year unlimited mileage warranty
Minus points:
Cabin a bit plastic, radio a bit rubbish (other than LW), need a step to get bikes onto roof, doesn't drive as well as a car, badge not the best (if you care)
