Dave,
I picked a good day to come back. Your new car is gorgeous, and I'm sure really, really quick on its feet. I am totally jealous.
As for speedo readings, my car decided on Saturday that "0" was a good reading...whether it was moving or not. A nice opportunity to learn about vehicle speed sensors, and a friendly reminder about how much my Honda dealer charges per hour. (See, Dave...a whine already, but it was subtle.)
