I think I'm now in the same boat now
Had the car two months and done around 700 miles so far. Majority of driving is motorway and due to running-in, I do around 65-70mph on most journeys with Cruise control on where possible.
The drone is evident at around 2200-2500 rpm, between 60-65mph. It doesn't bother me that much, but i think about it more due to the comments made on the forum.
