i just googled the mountain buggy page and they dont have the urban elite on there anymore? only the urban jungle, which im not sure is the same. They look pretty similar though. the elite has a bigger storage area underneath than the swift, and mine didnt have that bar bit at the front.
I also liked the fact that the handle bar is adjustable for when DH uses it. And it turns really well, you can drive it with one hand no problem. Its withstood some missuse over the years, i used to do the food shopping at the super market down the road and pile 20+ kgs of shopping in/on/around it and have DD in the baby sling and walk home! the only thing i might have changed is the fact that you cant turn DD around to face you once they are in the normal pram (after bassinette), she would have like to face me sometimes.
i think its the sort of pram that would last five kids if looked after well (should be for the price ), but i dont think they make a toddler attachment chair so if you had kids closer together i dont think you could turn it into a double.
