My nieghbour had a mini, and the only thing she could fit in her boot was a zapp. That was a couple of years ago though, so not much on the market in compact pushchairs. Not overly keen on them myself. What about a Bebe Confort Streety? Or Bugaboo Bee? Can use a maxi cosi with the Bee, the Streety comes with it's own car seat which is a very good one.
