Regular दिखाना गाड़ी Theory

Mr. Maellard says "Those carts aren't cheap." and makes Benson buy a new गाड़ी in the "Busted Cart" episode. But whenever a गाड़ी blew up and या crashed no one else seemed to care, and they seem to have an ABUNDANCE of carts available. Everyone says "The cart" but Maellard says "carts" which seems to दिखाना that at least he is aware of the multiple carts. In the episode where Benson gets super angry, he actually destroys a गाड़ी himself,but a विभाजित करें, विभक्त करें सेकंड later, Pops and Skips are seen driving a गाड़ी with two rows, which shows that there are multiple variants of carts as well.

So why did he have to get a new cart? Could it have only been because Maellard saw it himself? Possibly the characters refer to "the cart" as only one can be in use at any दिया time? Even so, why does Benson want to "replace" "THE CART" with a new, और futuristic one, implying that there was only ever one to begin with? Maybe he just bought ONE NEW CART, and possibly wanted to replace them all with the prototypes later on?

Also, in the zombies episode, Rigby says "Mordecai look! A cart!" using the generic form, indicating that somewhere there are और carts.

And in the SAME EPISODE, beforehand, Benson says "The गाड़ी needs a new suspension system."

So what do ya think, m8s? How many carts does the Regular दिखाना Park really have?
