In the case of Paloukas v. Intermountain Chevrolet  99 Idaho 740, 588 P.2d 939 (Idaho 1978), Paloukas ordered a new car from Intermountain and paid a deposit.  5 months later, Intermountain gave the deposit back and said there was a shortage of cars.  Paloukas sued for specific performance to get his car.  The Court found that there was nothing unique about the car.  UCC § 2-716(1) only allows for specific performance when the item is unique.  Also, since Intermountain had no car to sell, the Court felt that it "could not order the impossible."
