I've got an e46 convertible and now need a "convertible" seat for my son. I've been using the Graco snug-ride rear-facing seat in the back (sure the front seat has to go pretty far fwd but it's not too bad). Anyhow, it's time for the next type of seat (not booster), for kids 20-40lbs. It'll rear face. Anyone have any recommendations? I've searched the archives but found nothing for convertibles.
