Sadly, my 2000 Chrysler Concorde is limited to 118MPH. At that speed, it's very composed and feels fine, albeit loud. My mothers car will do 125 - also have toped that out. I routinely will do between 90-100 when I'm alone on the highways near my home. However, if there's any traffic at all, I won't drive over 80; or if people are in my car.
I've had a Jaguar XJ8 (2006) up to 130. That's the fastest *I* personally have driven. Empty highway, 4 miles of straight, alone, dusk, friend of the Statie who patrols that stretch of Interstate, along with a shiny, new $70,000 luxury cruiser.
