If you go with Ford Financing to get that extra $500 off, the APR is 4.9%. You can then refinance through your bank after 90 days. Most banks I believe have about a 1.99% rate so it's worth it. The dealer actually mentioned this scenario while I was talking with them and crunching numbers. Check with your dealer though as it varies as to where you live. In SoCal, they can get $2000 off instead of the $1500 where I live on the East Coast. This includes financing through Ford. So their rebate is $1500 without financing. My dealer said Ford gives better incentives to larger volume dealers/areas. If true, this doesn't make sense to me as it would help with sales in smaller towns with less disposable income compared to SoCal. Ugh.
