A corolla saloon thats been through minor accidents and is 13 years old vs a 2 years old swift and it isn't a fair comparison? for corolla i guess. and you are confusing harshness with power(like people consider vibrator cg125 better than gs150), faw has better low end torque and you are saying it lags behind in 2nd gear??? have you ignored knocking issues in 2nd gear of swift between 1400-1700 rpm(problem admitted by suzuki officials)? both cars are head to head in performance. mileage of that engine is in likes of civic(even worse than se saloon, altis 1.8) no where near city, it doesn't matter how calmly you drive, it won't cross 10-11 kmpl figure.
when did I said a word about jdm features(i believe my words were about quality of interior materials of faw which are comparable to jdm kei cars and even better than some eco models with lighter interior) although faw has some like adjustable headlights, factory fitted fog lights.
even if we assume that you are right, performance isn't the only priority for buying a car there are other points to consider like quality(rattling dash, water seepage in heavy rain, paint), comfort(back seat comfort??,suspension?), safety(outdated design, no. of airbags)
