I spec the 5-door because I have friends and relations who come to visit, using public transport, and I like to take them places.
And because we have a regular car-share rota for choir practice and it's a pain in the backside to have to keep leaping out and in outside everybody's front doors. I was the only one with a 3-door before I got the Golf, and it was a right pest.
Didn't worry me when I lived in England though, because I didn't have to transport friends nearly so often. And I did prefer the 3-door for me personally. It just depends on your circumstances.
