I would go for the Wira without hesitation. Why? The model is newer, this model was manufactured till about mid2000s, so it will be easier to get spares. Mechanicals are compatible with Lancer. Wira is a very rugged vehicle, very suitable for our roads. The car has already depreciated so there's nothing much to worry about resale value. Seriously Protons are the most underrated cars in Sri Lanka. You actually get much more car for money with a Proton. But it looks like a JCB molested a Lancer and gave birth to a deformed child.
Edit: Many typos corrected.
