Can a dealer be sued if they sell car as is?

In general yes, a car dealer can be sued after selling a car "as is," but the buyer's ability to successfully recover damages will depend on the specific circumstances and laws in the relevant jurisdiction. When a car is sold "as is," it means that the buyer is purchasing the vehicle in its current condition, without any express or implied warranties from the seller. As a result, the buyer assumes the risk of any unknown defects or issues with the vehicle.
