I would say if your car is not listed on the maxi-cosi list then it most probably doesn't have isofix points.
I have the Graco system with a base for the car seat and I love it. I wouldn't be without it. You just open the door and drop the seat on!! So easy and you don't have to mess about with the seat belt. Mine isn't Isofix but I will be using it. I'd recommend anyone get a seat with a base fixture!
