After much research, and finally finding time to get out and test drives some cars I have just ordered a dual cab Navara STX. Went for the auto deisel option. Thanks everyone for that answered my questions about manual v auto and diesel v petrol etc. Was also reading other members questions on hilux v rodeo v navara etc, all very informative.
Now I have to wait 6 weeks for delivery! Bummer, you can expect me up double island the weekend after it turns up!
Thanks again all.
