Is it permissible to sell a car that was involved in a rollover accident and meticulously repaired, so much so that no expert can detect the accident, without informing the buyer of that?

You must disclose to the buyer the condition of the car and any accidents or repairs it has undergone, even if the car appears to be in good condition. This is because concealing such information can affect the buyer's acceptance and the determination of the price. Honesty and transparency in selling bring blessings, while lying and concealment destroy them.
