Well,I have a 67 El Camino.
I call it a car.
Mines frame is longer behind the rear wheels than a coupe or sedan.More like the wagon frames.
It has factory air shocks too.
In 55,Chevy made a vehicle they called a truck,but is actually a wagon called a sedan delivery.
So,for me if it looks like a car-it's a car and if it looks like a truck-it's a truck!
Call it what you like!
And,what is a ute? (here we go again!)
Mike.
