I'm driving Mrs. Ontop's Mazda 6 today and was looking at the speedometer. I noticed that it tops out at 160. I've never done that in the car, or anything close to it, but judging from my experience with the car, I actually think it could make it all the way up there under the right conditions. So my question to you, is, have you ever hit your car's top speed? What was it like?

Alternatively, do you think the top speed listed is just an exercise in wishful thinking on your car?
