ok, as far as I know, the C* & 807 are almost identical. You can get the captain chairs in 807 too. tbh, seemed a bit of a waste of space. The driver & passenger seats are captain chairs, as are the very rear 2 (unless you go for bench option), sorry, they're not exactly captains chairs, are they, as they have no arms. the middle row can be 2 cpatain chairs or 3 chairs, but they're not bench, still 3 individual chairs, any of which can be in together/removed, so you could still have the isle down the middle & put in the 3rd seat as & when you need it.
I personally would go for the 7 seats & just have the 4 or 5 in that you need. It may be diff now, but in fact ours only came with 5 seats as standard & we had to buy as extras the rea 2 seats (had the option of a 3 seater bench or 2 individual seast, which is what we went for)
You could easyily seat the kids on the 2 outside ones & have the middle seat folded down as table, for eg, or have one kid in middle & 1 in back.
We did go for leather. i was concerned that it was light grey 7 would look dirtyu quickly, but it doesn't 7 in fact looks miles better than the black leather in the bmw which looked really filthy. i thought the fabric covers were all really ropey 7 the leather just wipes clean.
the swival front seats look better than they are. You can't swivel them while moving or abnything & in fact, they are not easy to swivel at all, esp the drivers seat. You have to be parked., so good if you're on a long journey mid winter.p*ing rain & stopping for pic nic. You have to move the seats as far forward as possible lean as far forward as possible then shove them round. the drivers one is even more complicated with steering wheel & handbrake to contend with. In short, it is fun when you finally sicceed, but we've only done it a couple of times. Definitely not a feature just to sort out a bit of argy bargy. Am I right in thinking you're still expecting your 1st child? You seem to be anticipating a whole heap of sibling rivalry lol! Actually the space between the driver/passenger seat, coupled with no handbrake/gear stick & flat floor is perfectly adequate for cross grown up to step through & throw a few well-aimed (verbal?) blows.
btw, get sat nav, absolutely indispensibe.
