How to Review an Auto Sales Contract
Stop the process and clear the desk
Read the final documents without sales conversation, countdowns, or blank spaces. Take enough time, ask for accessible copies, and leave if anyone prevents review. Do not sign because the dealership is closing, the lender is “waiting,” or the vehicle has acquired another mysterious buyer.
FTC guidance says to ask whether financing is final before leaving; if approval is still being worked on, consider waiting and keeping the current vehicle.
Match the parties, vehicle, and ownership facts
Confirm buyer and co-signer names, seller legal name, lender or assignee, addresses, full VIN, year, configuration, mileage, title status, lien information, trade details, and included keys or equipment. Investigate any mismatch with the vehicle, Buyers Guide, registration, quote, inspection, or loan approval.
Never sign a document with incorrect VIN or mileage on a promise it will be fixed later.
Rebuild the purchase price
Compare the final buyer's order with the written out-the-door quote. Recalculate selling price, discounts, rebates and eligibility, taxes, title, registration, seller fees, accessories, deposits, trade allowance, old-loan payoff, negative equity, down payment, and balance due.
Each number should have one name and one job. Watch for a deposit that vanished, a trade allowance offset by price, or an optional product reborn under an acronym.
Audit every add-on
Use the add-on checklist to match chosen product name, provider, cash price, term, coverage, cancellation, and signatures. Declined products must be absent from the buyer's order, installment contract, itemization, and electronic menu.
Obtain the complete product contract before paying. A brochure is not coverage.
Read the credit disclosure line by line
Confirm APR, interest rate, finance charge, amount financed, total of payments, payment amount and count, first due date, late terms, prepayment, security interest, default, repossession, insurance requirements, and arbitration or dispute provisions. Compare with the final approval, not an earlier estimate.
Multiply and reconcile carefully, allowing for stated rounding. Ask for a corrected contract when the explanation does not reproduce the figures.
Resolve conditional-delivery language
Ask whether the sale and financing are final and approved. Read provisions about assignment, spot delivery, returning the vehicle, changed terms, additional down payment, and trade handling if financing fails. Keep possession of the old car and title where practical until the deal is final.
Never sign a second, worse contract later without unwinding the first documents and obtaining independent advice appropriate to the situation.
Reconcile warranty and promises
For dealer used cars, retain the final Buyers Guide. Ensure as-is or warranty status matches the contract and every negotiated change appears in all required places. Put repairs, missing parts, second keys, delivery, registration, payoff, and refund promises in a signed due bill with deadlines and responsible parties.
Spoken promises are very lightweight cargo.
Collect a complete package
Before leaving, obtain signed copies of the purchase agreement, installment contract, credit disclosure, Buyers Guide, odometer and title documents, trade and payoff records, warranty, service contracts, add-on contracts, inspection, due bill, privacy notices, temporary registration, receipts, and cancellation forms where applicable.
Confirm insurance is active and the vehicle is legally and safely ready to drive. Follow any recall or defect instruction.
Verify after the transaction
Check lender welcome documents against the contract, confirm trade payoff with the prior lender, monitor title and registration, and verify cancellation credits. Report discrepancies promptly in writing and preserve dates, names, and documents. Contact the lender, seller, manufacturer, regulator, consumer authority, or qualified lawyer as the issue requires.
The signature should be the least surprising part of buying a car. If the numbers are still moving, the pen should not be.
