Car Seat Recommendations?

I have a Britax Boulevard CS. I think it is a bit more expensive than the Marathon, but I absolutely LOVE it! It is built extremely well, and I feel like my daughter could not be more safe when she is in it! I have a Impala and it fits in there just fine.

Ladies,

Thanks so much for all of the feedback.  It seems like the Britax has won..hands down.  That is what we are going to go with.

Thanks again!
