aging vehicles. the Frontier and 370Z haven't been changed in over ten years. the Titan needs to be discontinued and they have ruined the Pathfinder. I think it will be a while before we see a new Z, unless they do what Toyota has done with the Supra and rebadge another company's car. their quality sucks, so the need to work on that as well. good luck Nissan. you're going to need it.
