What does one-owner, clean-title, no-accidents really guarantee?

Not as much as it sounds. These descriptions are based on reported records, and a history report can miss unreported accidents, private repairs or maintenance gaps. They are helpful signs, but not proof of condition. Verify the claims with a history report and NMVTIS check, review service records, and get an independent inspection. OffLot shows facts without labeling a listing a good or bad deal, so you can judge for yourself.
