None of your business. But if you really want to know, well, you've got access to the world wide web - why not try a bit of research? I mean, I could tell you who it is, but given that the Stig's identity is *supposed* to be a mystery it doesn't seem quite right to just tell you. (It's probably not anyone you've heard of, though.)
Not sure why it isn't stevenflett's business?!? Isn't using this site using the world wide web? He did and , thanks to 4getmenot , now knows the answer.
