My Graphite saw more than 130 back in 2011 on a lonely piece of I75, I'd checked and knew there was no LEO in the four mile stretch - so I turned around and went for it early on a Sunday morning. The car seemed to "settle into" the road about about 110 or so.

The car FELT like it was comfortable at that speed -but I wasn't. I had to back off just because the legal risk was too much.

Cant remember but I'm pretty sure I had the top up but I can'[t really say for sure.
