The first one is pretty obscure. I doubt anybody will get it.

The second one will be almost instantly understood by any car guy.

The last will be almost instantly understood by every cobra guy, buit probably not many else.

I was considering "MY 42". Because, as we all know, 42 is the correct answer. A little obscure, but not by much.

But I ended up with "WHT NKL". Some get it, some don't.
