The contestant is shown three pairs of grocery items, one at a time. Each pair has a price displayed, and the contestant must select the item that correctly corresponds to the price. For each correct answer, the contestant may choose any of the digits in the car's price to be revealed; the corresponding card is then put in its slot.
- After the three prices have been guessed, the contestant must fill in the remaining slots correctly using the remaining cards to win the car. The car's price is then revealed by flipping over the game title.
