D. a dealer, contracted in writing to sell a Pontiac Sedan to M, a merchant. D, acting without legal cause, repudiated the bargain. Four months later M purchased a Pontiac (same model, same year) elsewhere. M sued D to recover damages for breach of contract. M contends that the car was intended for use by one of his salesman and that a large volume of business was lost because the particular salesman concerned, having no car for four months, could not cover his route effectively. M seeks to recover the profits thus lost for the four-month period in question. However, there was no evidence to show D knew, when contracting, that the car was intended for such use. Nor was there any evidence to show the price paid by M for the car purchased elsewhere. How much, if anything, will M recover from D
