P reached an agreement with D to buy a 2003 Toyota Tacoma for $16,971, less a $1,000 rebate, plus taxes and fees. The sales manager entered these numbers into a computer, which displayed a final price of $15,017.50. There was a computer error, and the price should have been $17,017.50. P attempted to write a check for $15,017.50 immediately, but the sales manager requested only a $500 deposit because the truck would have to be specially manufactured. The sales manager manually wrote on the sales agreement, '$14,517.50 due at delivery.' When the truck arrived at the dealership, D discovered the computational error, and he insisted that P pay an additional $ 2,000. P refused to pay the higher price and filed a complaint in the Harrison County Chancery Court. The chancellor entered judgment in favor of P and granted P's request for specific performance. D appealed.
