Highest I've ever gone in my SD was slightly off the 85 marking on my speedo when I was passing some lady in an audi A8 while heading up north, she looked over at me with quite an interesting expression
I think I was at around 87-90ish.....and I had LOTS of pedal left.......these things move.....with my new tires (awesome goodyear assurance) they are 130mph rated, and Smooooth on the highway, no vibrations at all anymore since I got them....so it makes it way too easy to "accidentally" cruise at 80
In general however, I drive mine like I stole it, its just way more fun that way.
