But remember, as offensive as it may be to our sensitivities, there are some people who actually will pay $80,000 for a Porsche because they LIKE them. Oh the horror! They could do the same thing with a Miata for a 1/4 of the price. What possess people to do such things? ....hmmm, I guess they can afford to...depressing. sl > > B. D.
