Zack is looking to get a new car. Anna works at a car dealership. Anna offers to let Zack drive away with the new car for $200 per month. Zack orally agrees. Zack pays $200 and drives away in the car. Zack believes he has bought the car while Anna believes she has leased him the car. Is this a valid contract?

Yes, because the parties agreed on a price and Zack paid it

Yes, but only if Zack would have leased the car for the same monthly payment

Yes, because Anna got $200 and gave Zack a benefit in return (the car)

No, because the contract was not in writing

No, because Anna and Zack did not have a common understanding of the terms of the agreement
