I wonder how complicated it is, people that sells License plate frames that has the Z logo (I'd say pretty representable) still went through the whole Copyright process....I'm sure they have to get permission and pay Nissan to manufacture those frames. Unless there's some loop hole I'm not aware of....i.e. not making it exactly the same. But remembering something from my engineering college course about patents and copyright, I think even if it slightly represents the company copyright logo, you may be infringing their patent. I just have to find out the process if we do this legally. That and also see if there's even a market for this as this initially wasn't an idea to make money. But like all business, in order to keep it running, you need to cover a lot of expenses and a profit to keep it running. Otherwise, why should anyone make things at cost when they could just make 1 or 2 for themselves and just call it a day?
Either way, while all this legal stuff is true, I find it kind of funny because we're simply putting a Z logo where it belongs....
