Varies by dealerships I believe, but they gave me scenarios from 3.99% and up (depending on credit score, down payment etc). They had 1.9% special financing, but with close to MSRP price. Too early for any customer friendly negotiations/incentives on 2017s at this point I think.
Should be 1.9% for everyone, as long as you are "well qualified":
