Perhaps obviously, this game would be played for a car. So here's how it works:
There's a screen roughly the size of perhaps a 75" TV in the middle of the prop. This screen has a virtual road that only goes straight and has grass and whatnot on the sides. A car facing forward is on the road. Prior to the reveal of the game, the car is described and the full price is given, so it's one of those games where the price of the car doesn't affect the game.
You are then given three small products. For each one, you must guess the price within $10 without going over. For each guess, a speedometer underneath the product adjusts the dial to the corresponding guess. After making all three guesses, the virtual car will start up and start driving at the speed of the first guess in miles per hour. A virtual speed limit sign with a pair of horizontally arranged traffic lights (one red and one green) will pass shortly afterwards. The number on this sign corresponds to the price of the first small prize. If the car is going at a sufficient speed (no more than 10 mph below the speed limit and no more than the speed limit itself), the green light lights up and the car continues. It will then speed up or slow down according to the guess for the second small prize. The process repeats. If the car successfully passes all three speed limit signs, the contestant wins the car. If at any time the virtual car goes too slow (more than $10 under) or too fast (over the price), the red light lights up and the game is over. Too slow and another virtual car will crash into the contestant's car. Too fast and the contestant's car will crash into a wall. Obviously the actual car the contestant is playing for simply sits on display.
Also, whenever an actual price is revealed on the screen, a display on the stand for the corresponding small prize lights up.
Another thing: small prizes in this game would never be over $100, but can be up to $99.
And one final thing: perhaps due to the difficulty of nailing all three prizes within $10 without going over, this game would only offer higher-end luxury cars (but not quite Golden Road cars; think cars that would be played in 3 Strikes)
