Have a 2.2 EX. It's a tardis with those rear seats – whether it's 4 people to a festival (stuff bags under the rear seats) or 3 people and all their scuba stuff (6x15l tanks, boxes, drysuits, etc) it seems to manage better than most estates up to A4/3-series size.
Haven't managed to fit a bike in across rear seats though with the front wheel off like the brochure – just ends up a bit too long (PA with 140mm pikes). Given the seats are one lever to pull to get a perfectly flat floor, I just do that, throw down a tarp and chuck it in.
What I do like is that the boot is wide enough to take a MTB or road bike, wheels-off and seat down, while keeping the seats up so it's all out of sight. Excellent if you need to park somewhere dodgy and can't take the bike in.
Si wasn't available when I got mine but is probably the best spec for the money now – seats are very nice, you get the better grille, USB port, etc. Just fit your own bluetooth phone (Honda's is rubbish anyway) and it's all you'd want really.
