Myself ...they are super rare so I just bought what I could. Car shows 5 miles under what I am actually doing but that is fine with me.
Honestly we need to get all these 3d scanned and shared with the community.
I have a blue one...if anyone else wants to team up I am willing to do my part to get the blue one scanned in. My library has a scanner.
