Anyone got a system similar to Maclaren XLR ?

Im looking for a single small umbrella fold stroller like my maclaren techno XT but with a carry cot for a baby and that a car seat can be clipped onto like the maclaren XLR system - does anyone know of anything similar ?

It will be for a newborn and a 3 year old ( the 3 year old could go on a buggy board on the back of this one as I really need a single for while the 3 year old is at school. if he doesnt want to be on the board id make sure i have a baby carrier under the buggy so could carry the baby and put him in the buggy.

I dont want a double as i already have a maclaren twin that i can use for days when i will need them both in it. I just want a nice light compact single. ( my main reason being we have a mercedes ML and the boot is tiny - literally i can fit a single buggy in it stood on its side and thats it - if i laid it flat it would be too wide !!)

Any help appreciated

if your after a really compact fold mothercare do the vio (suitable from birth) and bruin do a new version of their petite star zia that has a carry cot with it and reclines. Both fold like the quinny zapp
