I posted the thread about reusing my FPSVD that had been in my dad's car when he hit the deer and, after posting and reading the responses, had decided to trash it. Well, before I could trash it, I found out that a friend of a friend has a 3 year old in a backless booster because she can't afford a harnessed seat so I called Britax to ask about replacement after a crash. The CS lady told me the exact same replacement critera apply to Fisher Price seats they manufactured as they do to Britax seats. Since hitting the deer didn't meet those criteria, the seat I have is still okay to use.
So, anyway, I just wanted to share this in case anyone else is ever in this situation.
