Question: Thompson purchased a used car from Van Bortal Sales for $450. A clause in the written contract in boldface type provided that the car was being sold "as is." Another clause provided that the contract was intended as the final expression of the parties' agreement. After driving the car for one week, Thompson realized that the engine was burning oil. Thompson telephoned Van Bortal and requested a refund. Van Bortal refused based on the original agreement but orally gave Thompson a warranty on the engine for six months. The engine exploded three weeks later. Can Thompson collect based on the oral warranty given to him by Van Bortal?
