The Nissan Terrano is essentially a rebadged Renault Duster, and both models are now quite old. If you are happy with the car and its performance, you can consider upgrading to a new one. However, the Renault Duster will be making a return next month, and Nissan will also have its own version, which it calls the 'Tekton'.
We would recommend you wait to see those SUVs and then plan your new purchase.
