Obviously it isn't because of a huge cost savings. Just as we bought these old clunkers not for the cheap replacement parts. Perhaps both give a sense of purpose and satisfaction. One to save a style and class of automobile for for all to enjoy and the other to help in some way provide for a cleaner world. The "cost" factor is irrelevant (rational or not)in either case. __________________________________________________ Do You Yahoo!? Send FREE video emails in Yahoo!
