What common mistake is the user making in their PHP code for displaying the user's choice to buy a car?

The user is not correctly accessing the value of the selected car from the form input. To fix this, the user should use the $_POST superglobal to retrieve the value of the selected car from the form input. They can then use this value to display the user's choice to buy a car. 

// Retrieve the selected car from the form input
$selectedCar = $_POST['car'];

// Display the user's choice to buy a car
echo "You have chosen to buy a $selectedCar.";
