Based on the equipment and options list that MicroNut provided, there will be no NAV available on the 2008. That may kill any possibility of me taking delivery in the first year, as my wife will not consider any vehicle purchase without a navigation system. She is directionally challenged and can't figure out how a flat piece of paper (known as a map by many) has anything to do with where anyone may or may not be located on this globe. This is a big oversight by Smart. They have been offering NAV in Europe on the 450. I would think the 451 is big enough to handle one as well.
