I went to the baby shop the other day to look at my options and the attendant pointed out that because I have a dual cab (07 Navara) that a capsule would be a PITA to use as the belt adjuster (which needs to be loosened to remove the capsule, then tightened again, every time you take it out) will actually sit behind the back seat and won't be easily accessible. So that's one thing to keep in mind. No capsule for me, I'll have to stick with convertible.
