negotiated contract and found that finance officer made mistakes or withheld cost of added warranty. Made two or three corrections through closing process, finalized contract but did not take possession of car. It was too late and didn't want my wife to drive an unfamiliar car over unfamiliar roads. I have been thinking about the process of the close and don't have agood feeling about the finance officers attempt to disguise some of the costs. Since I didn't take possession of the car can I simply cancel the contract?
