My wife and I did European Delivery on BMWs a couple of times, back when they offered that to those of us in the US. The first time we did it I was following the break in directions to keep in under 100mph for the first 1,000 miles.
But on the second day we were passed by a minivan and then later that day by something like a Ford Fiesta. After that I started taking it up to 115-120 until we past 1,000 miles.
While we hit the limiter at 155 mph several times I ended up finding out that 135 mph
