I agree with the Nissan Vanette -- specially if CRDi. Also Mitsubishi Delica 4x4 CRDi and Subaru Exiga 2.0 Turbo. If these go into the market the Starex will surely lower its price and maybe add a 4wd variant.
I also want to see more smaller displacement Turbos and Kei cars ... I think these are the best way(s) for a poor country to be greener.
