An automobile retailer had an adult daughter who needed a car in her employment but had only $3,000 with which to buy one.  The retailer wrote to her, "Give me your $3,000 and I'll give you the car on our lot that we have been using as a demonstrator."  The daughter thanked her father and paid him the $3,000.  As both the retailer and the daughter knew, the demonstrator was reasonably worth $10,000.  After the daughter paid the $3,000, but before the car was delivered to her, one of the retailer's sales staff sold and delivered the same car to a customer for $10,000.  Neither the salesperson nor the customer was aware of the transaction between the retailer and the daughter. <p>Does the daughter, after rejecting a tendered return of the $3,000 by the retailer, have an action against him for breach of contract?</p>
