Wow.
Either you type very fast, or you don't take the time to read yourself back, because I don't even have english as my native tongue, and I have a hard time keeping up with your writing.
As for the point:
Of course, Rona
l doesn't have the right to sell copyrighted wheels made exclusively for BMW, but they do also sell other wheels not copyrigted by any other car manufacturer, thus rendering them as, also, an aftermarket wheel manufacturer.
As does BBS (who used to make wheels exclusively for BMW back in the days, as well as selling other model of wheels to distributors). They even made universal and double pattern wheels.
The fact of a copyright was never in dispute.
Just that to think that automatically a wheel made for BMW could be instantaneously better than an aftermarket is a misconception.
There are better wheels out there.
As most manufacturer of every horizon, a car manufacturer will build a product for as less as it could cost them, without being a piece of ?$/?".
And even that will depend on the manufacturer (remember Hyundai Stellar and Pony).

I hope I don't need to add to this point, which has been explaned in all sort and sizes.
If needs be, please PM me, as I won't add anymore information to this thread.
Thanks for reading !
PS: Here are old Ronal wheels... And new BMW Ronal.
