How as in what? power? comfort? features?

Power is sufficient, a fact that is also true for the 1.3 if you are a regular city driver. Naik genting both 1.3 and 1.6 also no problem, regardless of MT or CVT.

Comfort, 1.6 is worse due to the low profile tires on 15" rims. 1.3 is more comfortable, but still stiffer than FL and BLM. NVH is not so good, no sound insulation, you can feel every bump on your steering and your butt. Ride is pretty harsh.

Both 1.6 and 1.3 exec variants have 2 airbags, driver and passenger. The 1.6 comes with leather seats and bodykits (and the aforementioned 15" rims).

Naturally, a 1.6 engine would be more powerful than a 1.3, but that depends on your driving style whether you need that extra power. If you mom is gonna drive it, better to get a 1.3 instead due to relatively better comfort.

u can play techno and ppl mistaken it as woofer, how does that sound?
IMHO, 1.3 and 1.6 not far diff in engine power due to CVT, for city drive purpose. Correct me if im wrong =)
