Understand exclusions, conditional discounts, dealer fees and add-ons that can separate an ad price from the OTD total.
Capture the advertisement
Save the listing, timestamp, VIN, stock number, mileage, price and any fine print before contacting the dealer. Online listings can change, and a screenshot gives you a reference for the conversation.
Identify every condition
Look for incentives tied to financing, trade-in, loyalty, military service, college status or other qualifications. A price that assumes several conditional discounts may not be available to a typical buyer.
Ask what the advertised price excludes
The FTC advises buyers to obtain the OTD price in writing and watch for fees and add-ons that increase the cost. Ask whether destination, reconditioning, certification, dealer accessories and documentation fees are already included.
Keep tax and registration separate from dealer increases
Government charges can legitimately move the total above the advertised selling price. The key is to distinguish those charges from dealer-controlled amounts that were not clear in the ad.
Use the ad as a reconciliation document
On the buyer’s order, begin with the advertised price and trace every adjustment. If a charge is described as mandatory, ask who requires it, where it was disclosed and whether it is already included elsewhere.
Build the attainable-price test
Start with the advertised price and add back every discount for which you do not qualify. Then add dealer-required accessories or fees that are not government charges. The result is the price you can actually obtain before tax and registration, which is more useful than the headline number.
Repeat this calculation for competing ads. A vehicle with a higher headline price can be cheaper if its discount is unconditional and it carries fewer mandatory products.
Preserve the exact advertisement
Save a screenshot or PDF showing the vehicle, VIN or stock number, advertised price, date and conditions. Online listings can change, and an archived copy lets you compare the final paperwork with the offer you relied on.
If a condition is unclear, ask the dealer to state in writing whether the advertised price assumes financing through a particular lender, a trade-in, loyalty status, military or graduate eligibility, or other qualifications.
Removing unavailable discounts
An online listing shows $27,000 after a $1,000 loyalty credit, $750 military incentive and $500 captive-finance rebate. A buyer who qualifies for none of them should compare the attainable $29,250 selling price, then add fees and taxes—not treat $27,000 as the real starting point.
Questions to ask before agreeing
- What qualifications are assumed in the ad?
- Is the price tied to a trade-in?
- Does the price require dealer financing?
- Which mandatory products are excluded?
- Can you send the actual price for my qualifications?
- What is the price without any conditional incentive?
- Which required dealer products are excluded from the ad?
Frequently asked questions
Does an advertised price have to include tax and registration?
Requirements vary by jurisdiction. Regardless of ad format, request a written OTD total that identifies taxes, government fees and dealer-controlled charges separately.
What is a conditional discount?
It is a price reduction available only when the buyer satisfies a stated condition, such as using a specific lender or qualifying for a loyalty program.
Should I rely on a monthly-payment advertisement?
No. Payment ads can depend on term, down payment, credit tier and other assumptions. Compare selling price, OTD total, APR and total of payments.
Can a conditional rebate be included in an advertised price?
Advertisements can include conditions, but you should identify which discounts you personally qualify for and calculate the attainable price before comparing dealers.
Should I negotiate from MSRP or advertised price?
Use the actual VIN-level offer and complete OTD structure. MSRP can be a reference point, but the amount you must pay is what matters for comparison.
