This afternoon, I got a notification from Google Webmaster Tools that the number of soft 404 errors on our site (theusedcarplace.com) had suddenly increased. From the looks of it, all of the new errors are vehicles such as this (http://www.theusedcarplace.com/autos...ry-156429.html) that have expired or been removed from the site. How would I configure these to redirect to our existing 404 page so that these errors don't adversely affect Google's opinion of our site?
