The short version
"As is, no warranty" means the seller is promising nothing about how the car will run — and nothing more than that. Lies are still lies, the odometer still has to be disclosed, recalls are still fixed for free, and the factory's remaining warranty is the factory's to honor. What the checkbox really does is move all the verification to before the sale and put the burden of proof on you afterward. So do the work while it counts: inspect independently, pull the records the seller can't touch, get every claim in writing, and set a price that assumes you are the warranty now.
Most used cars in the US are sold with a box checked that says, in effect, whatever breaks after you drive away is your problem. On a dealer lot that box lives on the Buyers Guide taped inside the window. In a private sale there is no sticker at all — the sale is as-is by default. Buyers tend to read "as is" as one of two extremes: a formality that means nothing, or a blanket that lets the seller get away with anything. It is neither.
"As is" waives one specific, narrow thing: the unwritten promise that the car works. It does not waive the seller's obligation to tell the truth, the odometer disclosure on the title, the factory's own warranty if any is left, or a safety recall's free repair. Knowing where the line falls tells you what the paperwork will do for you (very little) and what you have to do for yourself (the inspection, the records, and the price) before the money moves.
The Buyers Guide: the one sticker that is part of the contract
The Federal Trade Commission's Used Car Rule requires dealers — businesses selling more than a handful of used vehicles a year, with the threshold set by the rule — to display a Buyers Guide on every used car they offer. It is the plain form in the side window with a warranty section split into two large boxes. One says the car is sold as is, with no dealer warranty. The other says the dealer is providing a warranty, and makes the dealer spell out whether it is full or limited, which systems are covered, for how long, and what share of parts and labor the dealer pays.
Two things about the form matter more than anything else on it. First, the Guide states that it becomes part of your sales contract and overrides any contrary terms — so a checked as-is box beats a salesperson's assurance that "we'll take care of you." Second, the form itself warns that spoken promises are difficult to enforce and tells you to get every promise in writing. Take that literally. If the dealer says the transmission was just rebuilt, that goes on the Guide or the buyer's order, or it did not happen.
The Guide also has a spot for a service contract. That is not a warranty: it is a separate product you pay for, with its own exclusions, deductibles, and claims process. Read it before you assign it any value in the price.
What "as is" actually waives — and what it can't
In sales law, a merchant carries implied warranties: that the thing sold is fit for its ordinary purpose (a car that drives), and, when the buyer relies on the seller's advice, that it fits the buyer's particular purpose. "As is" disclaims those. After the sale, a dead alternator or a failed head gasket is not the dealer's problem, however soon it happens or however obvious it seems the fault was already there.
That is the whole scope of it. Here is what an as-is sale does not touch:
- Fraud and misrepresentation — a seller who says "never been in an accident" over a car the paint gauge says was resprayed, or "clean title" over a washed salvage brand, is not protected by the checkbox. Lying about the car is a separate wrong from declining to warrant it
- Odometer disclosure — federal law requires the mileage to be disclosed at title transfer on most vehicles, and a false reading is a violation regardless of any as-is language
- State disclosure duties — many states require a seller to disclose known title brands, flood damage, or prior use as a rental or taxi; as-is does not cancel those
- Safety recalls — a manufacturer's recall repair is generally free at a franchised dealer for that brand whoever owns the car; run the VIN through the NHTSA recall lookup before you buy
- The factory warranty — that is the manufacturer's promise, not the dealer's; if time or miles remain it often follows the car, though some brands require a transfer step or reduce coverage for later owners, so confirm with the brand, not the seller
The catch: as-is shifts the burden of proof to you
The practical effect of "as is" is not that fraud becomes legal. It is that a dispute about a bad car stops being about the car and becomes about what was said. Without the disclaimer, you might have a claim simply because the car did not work. With it, you must show the seller told you something false and that you relied on it. That is much harder, and sellers know it.
So the paperwork you build before the sale decides whether "fraud is still fraud" is a comfort or a slogan. Save the listing with its photos and claims. Keep the text thread where the seller describes the condition. Get the mileage, the title status, and any "never wrecked" claim onto the bill of sale or the buyer's order. A seller who will say it but not write it has told you what the statement is worth.
Implied-warranty states and the dealer warranty box
Not every state lets a dealer sell a used car as-is. Some prohibit dealers from disclaiming implied warranties, and some require a minimum written warranty on used cars based on age or mileage. For those states the FTC publishes a different Buyers Guide, with the as-is box replaced by one explaining that implied warranties apply. Which states, and on what terms, changes over time — check your state attorney general's consumer page or your DMV rather than a list on a blog, including this one.
When the dealer warranty box is checked, read it like any contract: a limited powertrain-only warranty for a short window, with the dealer paying half of parts and labor, is worth something — but not a lot, and nothing on the electrical fault that strands you in week three. Never accept a verbal upgrade of it.
Private sales: as-is everywhere, by default
Implied warranties attach to merchants. A private individual selling their own car on Facebook Marketplace or Craigslist is not one, so the sale is as-is whether or not anyone writes the words down — no Buyers Guide, no warranty box, no implied promise that it runs. The truth-telling duties survive: odometer disclosure on the title is still federal law, and misrepresenting the car is still misrepresentation. But the same burden-of-proof problem applies, with a seller who is harder to find afterward than a dealership with a street address. And a "private seller" who is actually a dealer flipping cars without a license is using the private-sale label specifically to escape the Buyers Guide and every disclosure that comes with it.
Put "sold as-is" on the bill of sale anyway — your state's DMV form probably has a line for it. Then put the seller's claims next to it: VIN, mileage, price, date, title status, and any statement about accidents or flood you relied on. Two copies, two signatures.
When the paper offers nothing, do the work the paper won't
An as-is car is not a car to avoid; most good used cars are sold that way. It is a car where the verification has to happen before the sale, because nothing happens after. What replaces the warranty you are not getting:
- An independent pre-purchase inspection at a shop you choose — a seller who refuses to allow it has answered the as-is question for you; take the inspection checklist so nothing is skipped
- Records the seller cannot edit — decode the VIN, run the NHTSA recall lookup and NICB VINCheck, and pull the title history through an NMVTIS-approved provider; a free listing check sorts out what the ad's own details already contradict before you spend on the rest
- Service history and a paint and panel check — as-is sales are where an undisclosed repair costs you the most, so verify the body before you believe the story
- A price that carries the risk — you are absorbing every future failure, so the number should reflect the inspection's findings, not the asking price; build the offer from the car's actual condition and be ready to walk
- A bill of sale that records the seller's claims — the only paper that works for you in an as-is sale
