"As is" means exactly what it sounds like, and any buyer of any used car that's sold without a warranty who understands that knows they need to get their own mechanic to inspect the car before deciding to take title.
Assuming you didn't provide any written or oral warranty or representation, you have no obligations to the seller.
Avvo doesn't pay us for these responses, and I'm not your lawyer just because I answer this question or respond to any follow-up comments. If you want to hire me, please contact me. Otherwise, please don't expect a further response. We need an actual written agreement to form an attorney-client relationship. I'm only licensed in CA and you shouldn't rely on this answer, since each state has different laws, each situation is fact specific, and it's impossible to evaluate a legal problem without a comprehensive consultation and review of all the facts and documents at issue.
You owe no obligation to this buyer. Used motor vehicle is sold generally as-is unless you state otherwise. You provided no warranty. If they sue you, however, you will need to defend yourself in court - so watch your mailbox for a Complaint either in small claims or another court and make sure you comply with any deadlines in the mail. For example - if the Buyers file a complaint that requires you to answer within 28 days, you will need to file an answer and at that point I would recommend that you consult an attorney who can prepare a full answer denying their claims and asserting your defenses and to help you decide whether you need an attorney to appear for you in court. Otherwise, if you get sued and ignore it, you could end up with a judgment against you - even if you were right in the first place.
If you had the buyer sign something saying it was sold as is, then you may be okay. If not, then it is your word against the buyer's word on what the deal was. In a private sale in Ohio the seller’s only obligation is to answer questions truthfully, not hide anything, tell the truth about the vehicle mileage, not sell a dangerous-to-use vehicle, and sign over a clear title to the vehicle. There is no general 3 day right to cancel, or anything like that, in a car dealer sale or in a private sale unless it is part of the original deal. It’s true that buying or selling a car in a private sale can be risky business because the law is very different from a car dealer sale. In a sale between two people, neither of whom is a car dealer, in Ohio the only obligation on the seller is basically to answer the buyer’s questions honestly and not hide anything that the seller knows the buyer would want to know about. The seller has to tell the truth about the mileage on the car too by filling out correctly and honestly an odometer statement for the buyer to have. And many Ohio counties require a mandatory emissions test in order to get a vehicle licensed, but if the emission/pollution equipment was disabled or removed then the buyer may have the right to cancel the sale. But if the seller hides the truth or misleads or outright lies to the buyer, that can be an act of fraud and trying to claim it was sold “as is” won’t let the seller off the hook for fraud. There are some general tips at www.LemonUsedCarLaw.com too. Also Ohio does not have a used car lemon law at all. Next time, if you want to make the agreement clear so no dispute comes up later, the buyer and seller should consider writing out a “contract of sale” which says what the year, make and model and “VIN” number of the vehicle is, and also what (if anything) is being represented about the vehicle or if it is being sold “as is,” and then both of them sign it and each keeps a copy. But a written contract is not required in most states to privately sell a motor vehicle. Car dealers, however, have to use a written contract in every sale. To find out for sure what your obligations and rights are in a private vehicle sale in your state, you need to talk to a local lemon law lawyer.
