You know, the German luxury car? BMW Bayerische Motoren Werke AG, or in English, Bavarian Motor Works
I'm a bit confused at your assumption that it would be trademark infringement. There are several car dealerships that use sun and BMW in their name. If they used such a website why would it be infringing on BMW's trademark since they are obviously authorized to use "BMW" in their name? Thanks
If you are authorized to use the BMW in your domain name, then it is ok. Otherwise, it's a trademark infringement.
Correct. If the site owner has authorization from BMW, there should not be any problems. But publishing the domain/site without prior authorization is a trademark infringement. If you know how to find end-users, then try to sell it to interested end-users. I am not sure though why they would buy SunBMW instead of anything else which contains BMW.
