I was going to post this before I saw your reply. Fastest I've ever been on the ground was in my cousin's car coming back from Big Bend. Hit 155MPH. He did ask if we were OK with him opening it up to see what it could do. It's probably about as good a place as possible to do it on public roads (at least anywhere close to my part of the country) - long straightaway through the desert with miles of visibility. He got it out of his system and got back down to saner speeds for the rest of the trip.
