Sorry I was wrong about Sakhir Orange in the UK, it's about 20 cars not 5 or 6, still not a lot.
Odd you don't have a reversing camera, not many don't have it, it's really useful on a big car with not the best all round visibility. Given that most have the camera, or surround view, and it's a Sakhir Orange car, I'll take a stab and say the last 3 digits of your VIN are 441.
Wheel bolts were from Tikore in the USA.
