I was going to say.. I've never seen a dealer give a better APR than a credit union would. Plus you get the bonus $2000 (depending where you live) on top of the lower APR from the credit union.
As much as I want to say I envy the guys who are getting really quick EDD's, looking back at 4 nor'easters in the past month for NY makes me feel relieved that I'm looking at an EDD in later April!
I was thinking about doing the same thing but I'm not sure if the dealer has any say. However, we do have to take away 4 weeks due to the holiday shut down and then the plant shut down. I myself would be looking at a total of 19 weeks. (15 not including shutdowns)
