Cathy Signed a Contract on July 1 with the Local

Cathy signed a contract on July 1 with the local Ford dealer to purchase a Ford Venus for $18,000.This car was supposed to be delivered on August 5.On July 15,Cathy's grandmother unexpectedly died,and left approximately $50,000 to Cathy.Cathy's car had not arrived at the dealer by August 5.On August 7,she decides that with her inheritance she would prefer a nicer car.She goes to the dealer on August 8 and is told that her Venus will be in the next day.She tells the dealer that she is upset that the car is not in and that she would prefer a Ford Muskrat,which is a luxury model.She and the dealer agree on a price of $42,000 for a Muskrat to be delivered by September 15.By September 20,the Muskrat has not arrived.Cathy starts thinking that it would be wiser to use her grandmother's inheritance to purchase a house.She goes to the dealer and says that she does not want the Muskrat,and that she will take the Venus,which is still in inventory,for the $18,000 previously agreed to.Can Cathy get out of the contract to purchase the Muskrat? Can she force the dealer to sell her the Venus for $18,000?
