Steve agreed to buy a 1920 Rolls Royce from Cheree, a dealer in vintage cars. The agreed price was $350,000.When the time came for the handover Cheree informed Steve that she had changed her mind and would not part with it because it was a gift from her father and had great sentimental value. Advise Steve as to the appropriate remedy for the breach:

a)Where Cheree's Rolls Royce is the only one of its kind in the Southern Hemisphere.

b)Where there are many other 1920 Rolls Royce cars for sale throughout Australia but Steve would have to pay $50,000 more to purchase the cheapest of these.
