F&I add-ons what they'll pitch

Every item here is optional. Toggle one on to see exactly what it adds to your out-the-door price and monthly payment — most are quoted at 2-4x fair market cost.

Add-ons total $0

Government fees, itemized non-negotiable vs negotiable

Doc fee stays with the dealer and is worth questioning. Title, registration, and filing fees are usually fixed by the state.

Dealer reserve check apr markup

Dealers can mark up the real lender rate 1-2.5% and keep the spread. If you're not on the true 0% promo, ask for the buy rate and compare it here.

Reserve markup cost over full term

Cash rebate vs. low APR can't always have both

Manufacturers usually make you pick one. Compare total 5-year cost of each path.

Path A — your APR above, full price
Path B — rebate applied, standard APR

Check their number reverse-calculate

Dealer quotes you a monthly payment instead of a price? Plug it in here — this backs out the vehicle price they're actually charging, so you can compare it to your target.
