Is there a pushchair fit for a fiat 500?

I have only owned my little fiat for a little while. I'm now 5 months into my pregnancy and looking for a pushchair/ pram/ stroller. I can't seem to find anything that is compact enough to fit in my boot! 
Today I tried an oyster2 which just about worked but was a little over my budget. 
I was hoping anyone out there could suggest a pushchair suitable for a newborrn/ compatible with a car seat that may actually fold up small enough to fit in my tiny car. 
Much appreciated! Xx
