There's nothing to stop a facelift 7th gen being registered in 2005, should it have been available for sale, and vice versa the prefacelift, if it's sitting in a show room and it hasn't sold or gone onto being demo'd, it can be registered as late a you like effectively.
I have seen 7th gen accords registered in 2010 over here, also I've seen a 2004 registered Civic (ek4 Jap import 98 model) too!!
