It is on the web so it must be true.
Chrysler is committed to Sprinter through at least 2011. Fiat does have a similar offering, but since Sprinter is now established and is doing well overall, they may opt to continue that arrangement with Mercedes. Sprinter’s diesel gets Bluetec starting in 2010. http://www.allpar.com/reviews/2010/preview.html
Hopefully the 4×4 full time drive will come to the US also. I have a beautiful brochure from the UK advertising, among other things, that option.
