Seems like Saab has notched up a bit the development of the 2010 9-5 Sedan as we're seeing more and more prototype models making their appearance on public roads. In this video we see a whole parade of 9-5 Sedans camouflaged in the usual checkered theme. We're not entirely sure, but due to the number of people and vehicles seen in the film, it may be that this convoy of 9-5s was some sort presentation to selected journalists.Saab's replacement for the ageing 9-5 saloon is heavily based on the Opel Insignia with which it shares the same platform and engine range. Unless Saab decides to surprise us, the new 9-5 will make its world debut at the Frankfurt Auto Show this autumn.
