I'm not sure if this where I post this or not, but...
Just got my g37 so I'm doing all the stuff an excited new car owner does and that included merchandise shopping for my g37. I found zazzle had hats, shirts, hoodies, tote bags and probably key chaines and stickers and the like but I didn't loom beyond the clothes and tote bag. The thing is they're useing what looks like tou logo. As well as the logo they are useing G37 and Infinity in the text on the shirt. Though I read that you couldn't use that text on making your run of t-shirts. I did do a general search on the topic and saw no connection with zazzle and myg37, so sorry if I'm mistaken.

 

You can use the logo or text on whatever you like. However you can't sell or promote it here unless you're a sponsoring vendor.
