Mavic Carbone

Does seem like good deal. I just bought new and they were $1,000 (Down from $1,450 a few months ago). Only have a few rides with them, but I do feel positive difference. So pros/cons with going new/used. Obviously cost is factor, but new one's came with Wheel bags and confidence knowing where purchased will repair for me on call if needed (knock on wood). Plus not sure if big difference in 3 years based on same model... These are the Mavic Cosmic Carbone SL's correct? That is what I have now.
