Cara bumped into Cam at a party and offered to sell her beloved Camaro to Cam for $14,000. Cam knew the car and believed it to be worth at least $18,000. Cam low-balled Cara as he stuck out his chest and, somewhat arrogantly, said "That ain't gonna happen. I'll give you $9,000."

Cara, understandably offended at Cam's rude arrogance, said 'no'. A few minutes later Cam sheepishly walked over to Cara and said "I'll pay your full asking price, Cara - $14,000". Cara, still offended from his earlier rudeness, said she wouldn't sell it to Cam. If Cam sues Cara for the right to purchase the car, who wins and why?
