I need to replace a Britax Frontier carseat (that was in an accident) for a small 5 year old. I had planned on just getting the latest Britax Frontier, but wondering if I should be thinking about getting whatever the "next" carseat would be (not that I even know what that would be as I didn't think this would be on my radar for awhile)? Or just get another Frontier if it's going to last awhile? Thanks in advance for any advice/thoughts!
