I have found a link showing Class 8 market share for Navistar at 27.9% in April, 2009. The link causes the post to get deleted. I tried posting just the link and it said that links will be deleted to avoid spam. I will try to make the link not look like a link and post it separately.
When production was in Chatham Ontario they had 29% market share and gaining,a top, quality product low warranty cost and made the share holders money.Mexico now Springfield...maybe Alabama,build them as cheap as you want......good luck with the sales and share holder value.
