The american that said "Car Truck"? That's because we don't have a special word for the classical ute (integral-bed truck). We don't use the word "ute" except as short for "Sport Utility Vehicle" meaning more-or-less a tall wagon. This is a very common usage in the US -- "ute" for "SUV".

The Ranchero and El Camino have been described as many things. "Pickup" or "Truck" has been used to describe them, but it's not the most common usage I heard. Generally they were just called Ranchero and El Camino back in the days when they were actually sold. The El Camino was the car-truck-pickup-whatever version of the GM Chevrolet Chevelle/Malibu, while the Ranchero was Ford's variation of the full-size late 50's Ford, then in the 60's the Falcon compact, then Fairline and Torino mid-size vehicles into the 70's.
