I read that report as 750 total sold through mid-January (though that does sound low). Of course, availability wasn't that great during the Fall.
In the Northeast, each dealer around me has at least one (and one large dealer now has 4 in-stock). This dealer is knocking about $1k off MSRP now.
I imagine that the price/manual-only option is contributing, plus we're in the dead of Winter here. I still see discounts/rebates coming in 6-months to a year from now on the ST as time goes on, similar to what happened with the SVT Focus.
