Hello there. I’m wondering the same thing, but with a 2016 S Convertible, in the US. I see MINI-specific child seats requiring something called an “Isofix base,” which BMW uses, on the MINI website, but I’d love to hear contemporary real-world commentsI have a 2013 Mini Cooper convertible and have just found out baby number 3 is on the way! Can anyone tell me if they’ve used a doona with a convertible? Or recommend any prams/car seats that fit?!
