Car Seat for Nissan Juke?

Alex
Idk if this is the right board to post this, but I was wondering if anyone has a Nissan Juke, they have put a car seat in? I just paid mine off and was hoping to avoid getting a different car, but I read online that pretty much only a britax car seat will fit safely in it. Just curious if anyone else has one, and if they have found additional brands that safely fit. 
Also.. we are considering upgrading our vehicle for safety purposes for the baby. I'm just curious about whether anyone else has been able to make the car work for them. Thanks :)
