“A promise or an act may be a detriment although on balance the promisor is making a good bargain. Thus a promise to pay £10,000 for a Rolls Royce worth £12,000, is none the less a detriment, and a good consideration for a promise to deliver the car.” P.S. Atiyah, An Introduction to the Law of Contract 101 (3d ed. 1981).
