I thought I had something to offer but checked the website and there is nothing.
I was thinking there might be a wood inlay pen blank made/sold by kallenshaanwoods.com with a vintage car theme but there doesn't seem to be.
There was at one time but it seems to have been discontinued.
I know there was at one time because I have a couple of them in my inventory, but the design is very generic and not a specific vehicle model.
It's possible I was thinking of another company, lazerlinez.com, which also sells wood inlay designs but I don't see it there either.
The design was probably not a success, whoever had it.
