Well, on 2/18 I ended up ordering a 2013 Fusion Titanium. All that was available from dealers in the network were either base Titaniums or fully loaded - and seeing as I didn't want to pay the extra $4k for features I don't need, I ordered my custom car just the way I wanted it.
I was quoted 6-8 weeks by one dealer and 8-10 weeks by the dealer I ended up buying through (the first didn't have a titanium to test drive) and that makes today 7 weeks. So far, I've heard from the dealer once about 2½ weeks ago with a VIN and a build date of 4/1. I'm not sure when I should expect to get my vehicle, judging from the stories on the forums - but I'm beyond anxious to get my new car as I'm currently driving a 2005 Focus with 135,000 miles! It'll be quite the upgrade.
Here is the window sticker: http://fordlabels.webview.biz/webviewhybrid/WindowSticker.aspx?vin=3FA6P0K9XDR289692
I've heard that you should be able to derive the build date from the window sticker, but the information I was reading seemed out of date - hopefully the "03 27 13" indicates the build date because maybe that means it's ahead schedule? One can only hope! We all know the saying about wishing in one hand...
