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

quinny zapp takes the maxi cosi and you can sometimes get the frames on their own on ebay.

thank you, i will have a look on ebay tomorrow.
