I have a 2010 Clubman & currently use an infant seat for my 6 1/2 month old. I am looking to purchase a convertible car seat & would love to know which ones fit comfortably.

 

simpson makes a cool one.

 

I use this one in my Clubman. It fits fine. Thought I find my 2.5 year old can easily kick/touch the front seat with her feet no matter what position I have the front passenger seat at.

 

I used the Sunshine Kids line as they were built a bit narrower and highly rated. I just removed our convertible seat and replaced it with a Sunshine Kids Booster. I am actually going to drop off the convertible seat at a consignment shop so if you are interested...

Sunshine Kids Radian is what I have.
