F&I managers bury $3k in add-ons by quoting monthly payment bumps of $12

Finance and Insurance managers present extended warranties, GAP insurance, and paint protection as tiny monthly payment increases rather than total cost, making a $3,000 bundle sound like $12/month. This matters because 75% of buyers at some dealer groups end up with add-ons they never consciously agreed to, and those charges rolled into a 72-month loan at 9% APR balloon to over $4,500 by payoff. The practice persists because F&I is the single highest-margin department in a dealership, dealers face no legal obligation to present total add-on cost before signing, and the four-square worksheet deliberately obscures which line items changed.
