A practical checklist for comparing price, inspecting documents, arranging financing and confirming delivery.
Before contacting a dealer
Define the vehicle, budget and acceptable OTD range. Check insurance cost, recall status, likely registration costs and financing options. For a used car, plan for a history report and independent inspection.
Before visiting
Request an itemized OTD quote by VIN. Separate unconditional discounts from conditional incentives. Obtain financing quotes from more than one lender so you can evaluate dealer-arranged financing.
At the vehicle
Verify VIN, mileage, equipment, installed accessories and condition. Test drive the vehicle and confirm that promised repairs or accessories are written into the agreement.
At the finance office
Read the buyer’s order and financing contract without relying on the monthly payment. Review APR, term, amount financed, finance charge, add-ons, cancellation terms and whether financing is final.
Before leaving
Take copies of every signed document, confirm temporary registration and insurance requirements, understand title and permanent-plate timing, and do not leave a trade vehicle or down payment under terms you do not understand.
Create a deal file before you negotiate
Keep the advertisement, VIN, written OTD quote, trade appraisal, payoff quote, financing preapproval and any product brochures in one folder. A structured file reduces the chance that a changed number is overlooked when the deal moves from salesperson to finance office.
Record the date and source of each number. Payoff quotes can expire, registration estimates can depend on the address, and incentives can have eligibility or time limits.
Run a final five-minute reconciliation
Before signing, compare the final selling price with the written quote, verify each dealer fee and product, confirm the trade allowance and payoff, and check the amount financed against your cash down and equity. Then confirm the APR and term match the financing you accepted.
For a used vehicle, also preserve the Buyers Guide, inspection information, history records you reviewed and the VIN recall check. The purchase paperwork and vehicle-condition file answer different risks and both matter.
A clean sequence protects the negotiation
A buyer requests an OTD quote, receives outside financing approval, inspects the vehicle, checks the buyer’s order and only then compares the dealer APR. Because each step is documented, a changed fee or missing discount can be identified before signing instead of being absorbed into the monthly payment.
Questions to ask before agreeing
- Do I have the exact VIN and written OTD price?
- Have I checked insurance, recalls and condition?
- Have I compared at least two financing offers?
- Are every fee and add-on itemized?
- Do I have copies of all signed documents?
- Have I saved every final contract and product agreement?
- Did the final VIN, OTD and financing match my written baseline?
Frequently asked questions
Should I negotiate the trade and purchase together?
It is usually clearer to establish the vehicle price, then evaluate the trade allowance and payoff as separate parts of the same final worksheet.
Do I need an independent inspection for a used car?
A history report is not a substitute for a mechanical and safety inspection. Arrange one when practical.
What document matters most?
No single page replaces the others. Reconcile the advertisement, buyer’s order, retail installment contract, add-on agreements and delivery documents.
When should I discuss my trade-in?
You can establish the replacement vehicle price first, then value the trade separately. This makes it easier to see whether a high trade allowance is offset by a higher vehicle price.
What documents should I leave with?
Keep the buyer’s order, retail installment or lease contract, product agreements, warranty/Buyers Guide documents where applicable, temporary registration information and receipts for money paid.
