The Boat Tail Conundrum

Can someone help with this conundrum. I think I saw one of the three #Rollsroyce #BoatTail cars on a country lane in North Warwickshire on Friday. But data out there doesn't support the possibility of having the most expensive car in the region.

Some possibilities are

1. I have borderline #Hyperphantasia and created this imagery from seeing the image for about 2 secs. In other words, it was an illusion.

Possibility 2: #Beyonce & #JayZ are reported to have bought a #BoatTail and were in the UK recently around the same time, the car was unveiled on the banks #Lakecomo. Did a retainer drive the car around the UK?

Possibility 3: Was this a Prototype of the #BoatTail been tested. The region has some excellent Automotive test beds. But this begs the question, do #RollsRoyce create prototypes for exclusive coach builds?

Possibility 4: I saw a car towing a boat or yacht with the RR emblem and thought it was a #BoatTail.

Possibility 5: This was the second #BoatTail and was been tested prior to delivery? Youtube has a video showing the 1st #BoatTail in a Garage.

This leads to another question, would RR do this outside of its Total Vehicle Integration & Validation facilities in Goodwood?

I hope someone can shed better light on this?
