The Avanti is the Vahny
The GTI is Mein Fast
The Silver Hawk is The Studebaker ( despite the other two in the driveway )
The Miata, I call it Not The Solstice
The GTO was the Goat
The Grand Prix was the same, just pronouncing the x
The Dodge Ram 1500 didn't have a name as much as it had theme music which came from a video game called Monster Truck Madness.
Everything else pretty much was called what the factory intended it to be called.
