I think everyone will get a kick out of the following thread over on the Miata Forum. Please note the replies from 'bwob'. He really knows his stuff:

I've been on Miata forum for more than a year now, and bwob has some of the best comments ever. I love reading his posts.

Can we got Bwob over here?

I'll try. No promises, I believe he knows most about the Miata, not nearly as much about Mazda in general, though he is still very knowledgable.

Heh, bwob made my day :).

Edit: he's already here :D
