I can't believe the response to this thread, so thanks everyone! I will look at the web pages everyone has referred me to.
I'm going to check out what the two auction cars go for here in Utah on Thursday. I probably won't buy either one, but it is nice to see them and see what people are willing to pay for them.
I went to the preview, and I wasn't impressed with the yellow pushbutton. It was 4.6 DOHC-powered, but a bit rougher around the edges than I would have expected.
