Definitely look into that seat. You may need an angle adjuster to make it fit but I've seen people use that seat with the AA and get it to fit in just about ANY car rearfacing. If you have facebook, look up this group called "Carseats for the littles." They have car seat technicians on there that can help you with anything car seat! Good luck!!
