Interesting, I didn't know that. I hadn't considered the 7 series as too sporty, in fact I thought punters were keen on sporty models if anything, hence everything having a 'Sport' label on it these days. Unless I'm missing your point and you're referring more to the fact that the Audi and the Merc are more understated.
Warning: kids will destroy the inside of your nice car. There'll be **** and toys and mess everywhere. Leather is good as it is wipe clean but baby seats mark it easily. Consider this before spending a lot of money.
I'm not sure on the boot space, but the Lexus LS 460h is supposed to be very reliable and you can get a decent one for the money.

+1 for a Superb.
If you can find a V6 you're laughing.
I'd take a fully loaded Superb over a poverty spec F10 Amy day of the week.
