Yes. Nissan stopped Sunny production. Ghandara is basically responsible for killing the Nissan brand in Pakistan.
If they have anyone with brains running Ghandara, Nissan would have carved out a sizeable market share in Pakistan by now.
Anyway, why go for a Nissan AD? Its not the prettiest looking machine out there.
Suggestion would be - to go for a Lancer. Way better ride than Corolla.
Good luck either way.
