I considered regging this, too, yesterday, but decided against it. It's got a good number of google results and I'm sure you can push the value up with some development. However, I think the original meaning of the term is not viable (commercially speaking), so I'd be more inclined to develop it as a car racing or computer gaming site. Just an idea. In any case, I think it's worth the reg fee definitely and maybe worth developing or hanging on to for a while. With some promotion you might be able to get $50 if you want to sell it right away.
