I think the gear differentials are one of the trademark features of the Durango. €510.- is quite a bit more than the expected €400.- price tag, but still cheaper than I had originally expected. I just wonder how much cheaper the R version will be and what will be different... Maybe my brain will have a slight malfunction when I return after a 6-week business travel in late August and I'll buy one - "Oh darling, sorry, I didn't mean to, must have been the jetlag!!!"
