Mini Countryman - car seats

[edidxb]

Hi all,
I have a Mini Countryman which is a 2015 or 2016 edition - not the new one. I have been googling but can't find a definitive answer.
Can you use an isofix base in the back seats and can you fit in a pram as well as a car seat and possible a golden labrador!???
I am beginning to think that it is impossible but would to know if anyone else has managed.

Thanks.

I have a 62 plate model and you can pull the back seats forward. I used to fit a wheel chair in the boot and 2 grandparents in the back seats. I know it's not exactly the same, but I'm hopeful to fit pram babyseat and an extra large golden retriever in.

We have a Mini Countryman and it’s a bit of a squeeze but doable. We bought an UppaBaby CRUZ which isn’t small but it fits with one wheel popped off. Although I didn’t realise we could bring the sears forward which might solve that. We haven’t bought a car seat but I’m not expecting any issues. The boot will be pretty full with the peak though so not ideal for day trips etc.

There is a handle underneath the seats, like you would get on the front.
