Honestly, I wouldn't buy it. Not because it looks ugly which is not the case. Just because this merchandise is not from sega or at least Yu's team.
I doubt you have the rights to sell shenmue merchandise and I would recommend not to sell it. Many laywers just waiting for this kind of stuff appears on ebay.
I remember a german seller on ebay who sold N64 game cases with different Nintendo mascots on it. He got a letter from a laywer (from a merchandise company which have the rights to sell nintendo merchandise) and at the end he paid several thousand euros to the company and/or nintendo.
also i know about the trademark and all that stuff but i usually create models for personal use but wanted create something for fans of the series.
So why don't you provide the data for free?
