How about omit the roundel and go with an actual dot.
Then find a BMW emblem/sticker we can purchase seperately to place in front of the text.
This makes it look more appropriate and would emulate the logo up top much better without having BMW come down on us.
Regardless, if I get one of these, I will mod it so I can do that.
Also, while I doubt BMW would crack down on us at the moment as we are small, they could later (probably sooner than you think, trust me on that), having a setup that will never be an issue is the way to go. Get big enough and they will notice. Then we are stuck changing the design.
