In a recent flyer I received from Ford (F), I read about a promotion from Ford Credit offering 'An investment opportunity' called Ford Interest Advantage, of 1.10% interest for over $50,000, 1.05% over $15,000, and 1.00% for lower amounts, with a minimum investment of $1,000.
According to the letter, the investments are redeemable at any time, plus ther is unlimited checking. The small print says that these are unsecured debt obligations of Ford Motor Credit, and not guaranteed by Ford. These are not FDIC insured bank accounts.
The prospectus is available at fordcredit.com/FIA
