Nayar went to Toyota's Memorial Day sale to buy a new vehicle. While looking at the
prices of the vehicles she saw that the Toyota Prius and Toyota Corolla had similar prices.
The car salesman told Mrs. Nayar that the Toyota Prius was a better deal because it
came with a 100,000 miles bumper-to-bumper warranty. The warranty that came with
the vehicle was enough to convince Mrs. Nayar to sign a sales contract for the Toyota
Prius. Which body of contract law rules over the sales contract?
