8 Dealer Add-Ons to Avoid (And What They Really Cost You)

This is often presented as a necessary shield against fading, rust, and UV damage. Dealers sometimes claim it's already applied to the car. In reality, factory paint is designed to last the life of the vehicle under normal care. A quality ceramic coating from a reputable detailing shop costs a fraction of the dealer markup and is typically applied with more care.

Sometimes called Scotchgard, Teflon shield, or fabric protector. Dealers spray the seats with a protectant and charge hundreds of dollars for it. The exact same product — Scotchgard Fabric & Upholstery Protector — is available at any hardware store for under $15. If it's already been applied to your car, it has no bearing on the price you pay.

VIN etching involves etching your Vehicle Identification Number into the windows as a theft deterrent. Some insurers offer a small discount for it. However, DIY kits cost about $25 on Amazon and take 20 minutes to apply. Dealers charge $200–$500 for the same result. Some dealers pre-etch before the car reaches the lot — if that's the case, they'll say it's "already done." The price should still come down.

Extended warranties can make sense for certain vehicles, but the dealer's price is almost never the best price. Dealers mark up third-party vehicle service contracts substantially. You can purchase coverage from the same third-party providers directly — companies like Endurance or CARCHEX — often for the same coverage at half the cost. You can also buy an extended warranty from the manufacturer's website after purchase. Never let the urgency of signing prevent you from researching this independently.

GAP insurance covers the difference between what you owe on your loan and what the car is worth if it's totaled. It can be a legitimate product — especially on long loans with small down payments. But the dealer's version is often financed into your loan, meaning you pay interest on it for years. Your auto insurer almost certainly offers GAP coverage for $20–$50 per year as an add-on to your existing policy. Call them before signing.

This covers flat tires, blowouts, and wheel damage from potholes. It sounds useful, but check your auto insurance first — many comprehensive policies already cover tire and wheel damage. Additionally, most credit cards used to purchase or lease the vehicle offer some form of purchase protection that may overlap. The dealer's version typically contains exclusions and deductibles that reduce its actual value.

Modern key fobs are expensive to replace — sometimes $300–$500 from the dealership. This add-on covers replacement if yours is lost or stolen. However, many homeowner's and renter's insurance policies cover personal property including key fobs under their contents coverage. Some premium credit cards also include this under their purchase or travel benefits. Check before paying for a duplicate.

Dealers sell GPS tracking as a security feature, often with a monthly monitoring fee. The same functionality — and in many cases better functionality — is available for a fraction of the cost. An Apple AirTag tucked under the seat costs $29. LoJack offers factory-grade stolen vehicle recovery direct to consumers for $99–$199 with no monthly fees. Some dealers pre-install these and claim the cost is non-negotiable — it isn't.

Cartego's Add-On Alert feature flags each of these products in real time as they appear in your deal — showing you what each one actually costs on the open market and giving you the exact line to use to decline. You never have to remember this list in the room.
