Hey Mike,
Welcome! The new truck has loads of new improvements. /trucks.about.com/od/2005pickuptrucks/a/05_fseries_sd.htm Check out this link to explain some of the new improvements. Dash cluster is new and very nice also. Ford motor has a website for the 05 super duty alsofordvehicles.com/2005superduty/index.asp?bhcp=1. Hopefully this will convince you to go for the 05. I know I just ordered an 05 350 myself. As far as cars direct I have never dealt with but there are is a guy I beleive that helps run the site that gives square deals. Yeti may be able to connect you with the right person. Good Luck
