Yeah exactly, the Real Driving Simulator... not necessarily racing. Sure, in the end that's what we're all here to do--gotta get those gold trophies. But that doesn't mean we don't also want a wide variety of vehicles to test drive in the simulator as well, whether it's just doing donuts in a Crown Vic or thrashing a little runabout like a Mazda Protege around our favorite track as fast as we can. So yeah, some may argue vehicles like the Nissan Leaf and Ram 1500 have no business in a game like GT, but I say the more variety the better. Especially cars that were significant in history for one reason or another, and I think the Crown fits that mold.
That being said, I'd prefer the most basic, stock, factory example of a given car to see what it could do straight from the manufacturer, so I'd still say I'd rather a "civilian" example than a police unit with some random city's police livery, then we could mod it as we see fit. The black steel rims would be cool to have as an option in GT Auto.
