<P> Typical offers from auto companies are "Zero Percent APR financing available or $1,000 rebate ." The consumer who elects "zero percent" financing gives up a $1,000 rebate (reduction in car price). Effectively, he or she pays $1,000 to get the "interest free" loan . Since only auto makers can do this type of bundling, banks, credit unions and other competitors are left at a disadvantage . They must disclose true APR rates while the auto makers can claim no interest costs . In the process, the typical consumer is left with a complex finance problem .
