Why would they? They are already offering more gizmo's; (please see shameless copy n paste of my own post below). If they start offering more they will a) add cost b) reduce profit c) eat into Civic's sales.
If either of pakistan's two major manufacturer's or even pak suzuki for that matter, ever cared for end users they would stop offering manual windows, non-ABS cars, non-airbag cars, non-immobilizer cars, cars without A/C filters. They are all here to make money the best they could by limiting option so that if you want a particular feature you must buy a higher cost product:
The best example is XLI and GLI and Civic vs Civic Oriel. The former is well known; for Civic honda does not feature Alloy rims or auto-folding ORVMs even as an official option (at-least for latter). They could easily do that; but noooo, please pay us more and buy oriel even if you dont want the sun-roof!
As for competition, Honda is, City in this case, generally sold to urbanites, very few rurality based people buy honda. In urban areas, most women with purchasing power opt for City esp. those working in telcos drawing decent salaries and no obligations of running the house. Similarly men in these companies prefer Civics (even though they might have obligations like wife and child(ren); their wives are mostly working and are mostly one child families).
Toyota is bought my uncles and rurality based folks generally. There are of-course young people, like my friend, who would buy a toyota irrespective of looks or features as at the end of the day he considers resale paramount.
My observations are based mostly on what i see in ISD and may or may not be applicable to your city. But I am sure these generalizations would generally stick to other cities as well.
Here's what the 1.3L will offer over the XLi
1. Power Windows 2. ABS 3. More powerful and fuel efficient engine 4. Option of an Auto which does not break the bank
Here's what the Aspire will offer the GLi, in addition to what the 1.3L already offers
1. 1.5L Engine 2. Navigation 3. Leather Interior 4. Alloy rims 5. Super cool digital meter (maybe)
6. Body color mud flaps (yeah, nothing to write home about, but hey it is something)!
