Thnx, Rolfe - I ordered the car almost three months ago and have only made one change (manual to DSG) - since putting in the order, I've only posted messages in response to other people's postings - so I'm having a bit of a wobble
I honestly think you should wobble in the direction of the 5-door. The sheer convenience factor for someone with a family like yours should make it a no-brainer. I think you're being over-cautious about the safety aspect, and indeed you may well be outright wrong. I don't think VW put in rear airbags to make the rear seat more dangerous for children, and someone already mentioned additional strengthening in the 5-door.
I've always had 3-door cars up till now, and prefer then for myself alone, but I had my arm twisted to get a 5-door and I have to say that when you're carrying more than one passenger it's an
enormous advantage. As you have children and will be using the rear seats constantly, I think there's no contest.
Rolfe.
