Pushchair chassis which takes a Maxi Cosi car seat?

[duende]

I am after a second hand puschair chassis on to which i could fix my Maxi Cosi car seat. I bought a Pliko Pramette before my DS was born - unaware of how easily he would fall asleep in the car and how nearly impossible it would be to get him to sleep anywhere else
so I am now looking for a chassis that would be very small when folded - needs to fit into a boot of a yaris and that would go with the MC. any suggestions will be much appreciated

Fits on Zapp chassis, probably the smallest frame folded.

um, micralites, streetys ( I think) zapp defaintely smallest.

thank you ladies, it sounds like zapp is going to be the one.
