I knew there was a really spiritual reason that I drive around the piece of crap that is the Jeffmobile ('95 Chevy Corsica - 180k miles - paid off).
Check out http://www.junkycarclub.com/. This is a new thing from the guys that brought us xxxchurch.com. They are challenging the masses to give up their sweet rides with big car payments and settle for a paid-off ride that might be junky. Why? They want us to live with less so we can give more. Sacrifice some bells and whistles and sponsor a child instead - that sort of thing. Great stuff.
