Rumors say that Japanese carmaker Nissan will introduce soon an improved version of the 370Z sports car series. The debut will take place this year at the Chicago Auto Show. Unfortunately this is all we know about the modifications that will be brought to the 2013 model year, so not much. We will still have to find out if they are thinking of a full facelift or only just small changes here and there. The standard model was first sold as the Fairlady in Japan after being introduced back in 2008 at the Los Angeles Auto Show after the 350Z. The improved 370Z model will not be the only one revealed at the show, but the pre-production 2013 Pathfinder and also the 2013 GT-R will also be there. Nissan will introduce a specially modified version on the NV van as well. The 2013 Pathfinder Concept features 3-row seating for seven passengers, four-wheel-drive and dual panel moon-roof.
