You just summed it up! As I detail in my post though, this is a specific homage to the pre-1997 lincoln town car and more distantly the 1987 buick GNX (the rear ends look totally different, but still). There is no other conclusion you can make if you look at the styling, I mean obviously there are asian minimalist car design cues here too from cars of that era (particularly, and beautifully executed, in the rear face and lights of the car), not trying to downplay that, this is just such an obvious nod to a precise part of U.S. car culture and it is cool because whoever had the vision for this car has REALLY fucking good taste in cars.
