Professional Deal Review · $249 · one deal

Negotiate your best deal. Then show it to us.

Upload the dealer’s worksheet or buyer’s order and a FMYCAR advisor validates every line (price, trade, fees, rate, term, add-ons) and tells you exactly what to fix before you sign. Typical clients find $800–$3,000 of markup, fees and products they didn’t need; typical, not guaranteed, and if the deal is clean we tell you to sign.
