Dealer add-ons and market adjustments

Add-ons are the products a dealership attaches to a car beyond the manufacturer's specification — paint and fabric protection, nitrogen tyres, VIN etching, tracking devices, extended warranties — and a market adjustment is simply a charge above sticker when a model is scarce. Neither is a government fee, neither appears in the tax, title and registration figures on this site, and both are negotiable price, not fixed cost. They are also usually taxed, so a $1,200 package in an 8% state really costs about $1,296. Contrary to widespread reporting, there is currently no federal rule banning them: the FTC's CARS Rule was vacated by the Fifth Circuit on 24 January 2025.

The two kinds, and why the difference matters

Pre-installed add-ons are already on the car when you arrive, often as a “protection package” on a supplementary sticker beside the window label. The dealer will say they cannot be removed, and physically that is often true — you cannot un-etch a windscreen. But the *charge* is still price, and price is negotiable. Ask for the amount off the vehicle, or ask what else is in stock without the package.

Finance-office add-ons — extended warranties, gap insurance, service plans, tyre-and-wheel cover — are offered after you have agreed a price, when fatigue is highest and the monthly-payment framing makes a $2,000 product sound like $30. These can simply be declined, and declining them does not affect the deal you already agreed.

They increase your tax as well

Add-ons that form part of the vehicle sale generally go into the taxable price, so they cost more than their face value. That works in your favour when you remove one: taking a $1,500 package off a deal in a state at 7% saves $1,605, not $1,500. It also means an add-on-heavy quote inflates the line the dealer may describe as “taxes” — which is exactly why the government portion is worth knowing independently before you sit down.

On the same $30,000 car, statutory charges across the 15 states published here run from $555 to $3,377. Anything your worksheet shows above your state's figure is the dealership's, not the government's — how this site draws that line explains what is and is not included.

The names you will actually see

Worksheets rarely say “add-on”. They use official-sounding labels, and buyers reasonably assume anything that looks like a fee is a government one. None of these are:

  • Dealer prep fee. Charged for removing shipping plastic and checking fluids — work the manufacturer already pays the dealer to do.
  • Advertising fee. Your contribution to the dealership's marketing. Sometimes a real regional-association charge passed on, sometimes simply margin.
  • VIN etching. The vehicle identification number etched into the glass as a theft deterrent, commonly a few hundred dollars for a few dollars of materials.
  • Wheel locks, nitrogen tyres, pinstriping, fabric and paint protection. The classic pre-installed package, usually presented as already fitted and therefore non-removable.
  • Anti-theft or tracking devices. Sometimes bundled with a warranty against theft loss, which is what makes them harder to refuse than the rest.
  • GAP insurance and extended warranties. Legitimate products that are worth money to some buyers — but optional, available elsewhere, and frequently described as conditions of the loan when they are not.

The test is not whether a charge sounds official. It is whether the state sets it. Tax, title and registration are the only lines fixed by statute, and the quote checker will tell you what those should total for your state and price, so everything above it resolves into one negotiable number.

The trap that costs the most: conditional offers

The expensive version of this is not a fee at all. It is an advertised rebate or a headline finance rate that turns out to depend on something — financing through the manufacturer's own lender, falling into a particular credit tier, being a recent graduate or a returning customer, or buying an extended warranty to “qualify” for the rate.

Advertised incentives are also frequently stacked: several offers totalled into one attractive figure that no single buyer can actually claim at once. Ask which specific incentives you qualify for, in writing, before treating any of them as money off — and treat a rate that requires a product purchase as what it is, which is a more expensive rate with a product attached.

The legal position, accurately

The FTC finalised the CARS Rule (Combating Auto Retail Scams) to require upfront pricing and to prohibit charging for add-ons that provide no benefit. It never took effect. On 24 January 2025 the Fifth Circuit Court of Appeals vacated it, holding that the Commission had exceeded its authority over practices that were not inherently deceptive and had failed to give adequate notice of the rulemaking.

A great deal of content published since then still describes the rule as though it were in force. It is not. What remains is Section 5 of the FTC Act, which prohibits unfair and deceptive practices generally, and state consumer-protection law — and several states have moved to legislate in the gap the vacated rule left. The practical consequence for a buyer is unchanged: your protection is the out-the-door number you agree in writing, not a federal rule.

How to get them off the bill

  1. Know the government portion first. Run your price and ZIP through your state's calculator, or paste the quote straight into the quote checker, so you can recognise a real fee when you see one.
  2. Ask for the out-the-door price in writing, itemised, before you visit. Add-ons are far easier to remove over email than across a desk.
  3. Separate the lines into three groups: statutory (tax, title, registration), the documentation fee, and everything else. The third group is the conversation.
  4. For pre-installed items, negotiate the vehicle price rather than the line — the dealer usually cannot delete the charge but can always discount the car.
  5. Decline finance-office products at the time, not in principle. You can buy a warranty later; you cannot easily unwind one financed over six years.
  6. Re-confirm the final out-the-door total in writing before signing, and check it against your own figure one more time.

Frequently asked questions

What are dealer add-ons?
Products and services a dealership adds to a vehicle beyond the manufacturer’s specification — paint and fabric protection, nitrogen-filled tyres, VIN etching, anti-theft tracking, pinstriping, extended warranties and service plans. Some are installed before you arrive and presented as already part of the car; others are offered in the finance office. None of them are government charges, and none appear in the tax, title and registration figures on this site.
Do I have to pay for add-ons already installed on the car?
Not necessarily. If the item is physically on the vehicle — tinted windows, a tracking module, applied paint sealant — the dealer may decline to remove it, but the charge for it is still part of the price you are negotiating. The practical route is to treat it as price rather than as a fee: ask for the equivalent amount off the vehicle, or ask for a different car from stock without the package. Items not yet installed can simply be declined.
What is a market adjustment?
An amount added above the manufacturer’s suggested retail price when a model is in short supply — sometimes labelled "market adjustment", "additional dealer markup" or "ADM". It is not a fee and not a tax; it is the dealer charging more than sticker. It is fully negotiable, it varies enormously between dealerships for the same vehicle, and it also increases your sales tax, because tax is charged on the price you actually agree.
Are dealer add-ons taxed?
Generally yes. Add-ons that form part of the vehicle sale are usually included in the taxable price, so they cost more than their sticker amount: a $1,200 protection package in an 8% state adds roughly $96 of tax on top. This is one reason removing an add-on saves more than its face value, and why the out-the-door total is the only figure worth comparing between dealers.
Did the FTC ban dealer junk fees?
No — and this is widely misreported. The FTC’s CARS Rule (Combating Auto Retail Scams), which would have required upfront pricing disclosure and banned charging for add-ons with no benefit, was vacated by the Fifth Circuit Court of Appeals on 24 January 2025 on the grounds that the FTC exceeded its authority and failed to give adequate notice of the rulemaking. It is not in force. General prohibitions on unfair and deceptive practices under Section 5 of the FTC Act still apply, as do state consumer-protection laws, several of which have since been strengthened.
What is a dealer prep fee?
A charge for preparing the car for delivery — removing protective shipping material, checking fluids, washing it. Manufacturers typically already compensate dealers for this work through a delivery allowance, which is why the charge is widely criticised as duplicate. It is a dealer-set price, not a government fee, and it is negotiable like any other part of the vehicle price.
What is an advertising fee on a car purchase?
A charge passing the dealership’s marketing cost on to you. In some regions a genuine advertising-association assessment is billed to the dealer and passed through; in others the line is simply margin with an official-sounding name. Either way the state does not set it and it forms part of the price you are negotiating.
Why is the advertised rebate not in my final price?
Advertised incentives are frequently conditional or stacked. A headline figure may combine several offers — loyalty, conquest, recent-graduate, military — that no single buyer qualifies for at once, and the best finance rate often requires using the manufacturer’s own lender or falling into a specific credit tier. Some offers are presented as requiring an extended warranty purchase. Ask which incentives you personally qualify for, in writing, before counting any of them as money off.
How do I tell an add-on from a government fee?
Calculate the government portion for your state first, then compare it against the dealer’s itemised worksheet. Tax, title and registration are set by statute and identical at every dealership in your state. Any line beyond them — however official the name sounds — is the dealership’s own charge. A line labelled as a fee is not necessarily a government one, and in some states describing it that way is itself unlawful.
