A mechаnic wаs rebuilding аn antique car in his garage. One day, a wоman cоmplimented the mechanic's wоrk on the car. The mechanic told her that the car should be done within the next week and offered to sell it to her for $100,000. The woman wanted to think about it, so the mechanic told her that he would hold the car for her for a week. Two days later, the woman discovered that the mechanic had just sold the antique car to a foreign collector for $150,000. She immediately went to the mechanic's garage and discovered that the car was still there. The woman told the mechanic that she accepted his offer to sell the car for $100,000, but the mechanic explained that he had accepted another offer and could no longer sell the car to her. The woman subsequently brought an action against the mechanic for breach of contract. Is the woman likely to succeed in her action against the mechanic?
