Small boot - can you recommend a travel system?

[dingdongdigeridoo]

I'm starting to look at travel systems, but a lot of them seem to be really massive even when folded. I have a Corsa, so the boot isn't huge, and not really keen on buying a bigger car! I like the convenience of having a car seat that simply clips into a frame, so is there one that'll fold down nice and small and fit in a hatchback?

Bugaboo Bee or Babyzen Yoyo+

Came on to recommend the YoYo or the Bee only to see John has beaten me to it!

I have the YoYo and love it, I think all in it’s slightly cheaper than the Bee and we travel a lot so the YoYo won out as you can take it onto a plane as a carry-on as the fold is so tiny. Both great buggies/travel systems though!

We've got a tiny car as well and these are what we've shortlisted for boot compatability, also car seat reasons! :) I have only gone for buggies which can be used from birth lie flat parent facing ie need no carrycot, because I can't imagine where on earth I would put the carrycot in the car, so I think it's a waste of money. Unfortunately this does make them a bit more bulky than the super lightweight ones. But I found acceptable, these all fit in world's tiniest boot with seat unit on but would be even smaller if using with car seat.

In personal preference order:
Cybex Balios S
Mutsy Evo
Joie Chrome
Hauck Soul Plus (unfort. only available with carrycot but you don't need to use it)
