F&I Add-On Products
GAP InsuranceCommonBuy through your own insurer — same coverage, fraction of the price.
Extended Warranty / VSCNegotiableOnly consider manufacturer-backed plans. Third-party VSCs have poor claim records.
Prepaid MaintenanceNegotiableDo the math: plan cost ÷ services = your breakeven. Most buyers lose money.
Tire & Wheel ProtectionNegotiateIf you want it, negotiate hard. Independent tire shops are cheaper for one-off repairs.
Dent & Ding ProtectionAvoidIndependent PDR shops charge $75–$300/incident. Dealer plan rarely pays off.
Windshield ProtectionSkipAuto insurance comp covers most glass. Safelite SafePlan is cheaper if you want a supplement.
Key ReplacementSkipHomeowner's insurance or credit card may already cover it. Aftermarket fobs cost $70–$180.
Credit Life InsuranceSkipTerm life through an independent insurer is 3–5× cheaper and protects your whole family, not just the loan.
Credit Disability InsuranceSkipFine print kills claims. Check employer STD coverage first. Standalone disability is far better value.
Theft Protection / GPSSkipDIY tracker (AirTag $29, Bouncie $68) does more than dealer GPS at 10% of the cost.
VIN EtchingSkip$18 DIY kit from Amazon. Dealer charges $200–$400 for the same result.
Paint Protection / Appearance PkgAvoidDealer sealant lasts 6–24 months. Pro ceramic coating ($700–$1,700) is worth it — but not from the F&I office.
Rustproofing / UndercoatingAvoidModern cars have factory rust-through warranties. Electronic modules have no peer-reviewed evidence.
Nitrogen Tire InflationSkipNo measurable benefit over free air. Buy a $10 tire gauge and check monthly instead.
Accessories PackageAvoidDemand itemization. Remove by name or use as a closing leverage chip on the selling price.
Pulse Brake Light ModuleAvoidLikely violates FMVSS 108 (flashing brake lights required to be steady). Demand removal in writing.
Excess Wear & TearNegotiableLease buyers only. Check if your credit card already covers it. Buying? Skip entirely.
Dealer Fees
Documentation FeeCommonReal fee, real markup. Use it as selling-price leverage: "What can you do on the vehicle price to offset the doc fee?"
Dealer Prep / PDI FeeNegotiableManufacturer reimburses the dealer for PDI. The fee on your contract is extra margin — push back.
Advertising FeeNegotiableAsk for documentation. If legitimate, offset against selling price. If vague, push for removal.
Market Adjustment / ADMAvoidEmail 3–5 dealers for OTD quotes before you walk in. Competing quotes eliminate ADMs before negotiation starts.
Reconditioning FeeAvoidUsed/CPO only. Recon cost is already in the retail price — charging it again is double-dipping.
E-Filing FeeNegotiableActual state DMV e-filing cost is $5–$15. Stack with other fee asks for one combined OTD reduction.
Government & Tax Fees — Set by Law, Not Negotiable
Sales TaxRequiredLower selling price = lower tax. Trade-in credit reduces taxable amount in most states.
Title FeeRequiredFixed by state law. $15–$150 depending on state. Not set by the dealer.
Registration FeeRequiredState-mandated. Look up your state's fee calculator to preview before signing.
License Plate FeeRequiredTransfer existing plates — usually $5–$20 cheaper than new plates.
Emissions / Safety InspectionRequiredOnly applies where your state/county mandates it. New vehicles often exempt for 1–5 years.
Temporary TagsRequiredNominal ($5–$25). Keep visible until permanent plates arrive. Transfer plates to skip temp tags.
