Be aware though that some of the "Credits" BMW financing offers only applies if you use their financing, and if you go outside of BMWNA Financing, you don't qualify for those credits.
I believe their best rate when we bought ours back in June was 3.05% when we were able to get below 2% using outside financing....doing that meant we didn't qualify for the credits (turnkey and loyalty...about $1250 worth) which was a bummer, but the amount we saved on the life of the loan with the lower interest rate more than made up for missing out on the credits.
