JDM vs PKDM Wagon R - Confused about CC and AC performance

[729waqar]

Assalamu Alaikum.

What should be preferred choice between JDM Wagon R (660cc) and Locally made Wagon R (1000 cc)? My focus is on following:

1. Fuel Average (Important)
2. A/C performance (Especially in June/July)
3. Engine life (If planning to keep car for 5-10 years)
4. Cost Range (2.5 to 3.2 million)

Also is engine CC linked to AC performance? I've heard that lower 660 CC engine heats faster on A/C as compared to 1000 CC Engine.

I know there are older threads about JDM vs PKDM but since the release of recent Stingray and FX/FZ model, what should be preferred choice for buying a Wagon R for family use (both within city and on long tours)? If there is another car that surpasses these criteria, I'd also like that.

AC is strong in both JDM and PK versions however the PKDM version has overall better AC due to bigger engine where the compressor does not cutout even when accelerating hard as it can cope with the extra load. Engine is bigger and more powerful in PKDM version. Economy is the same more or less, depends largely on driving style.
The PKDM is manual gearbox with the exception of AGS variant (AGS is also a manual gearbox just operated by a computer). Proper cvt auto is in JDM version.
JDM version will have a lot more options for safety such as airbags, ABS etc.
Parts for local will be cheaper as compared to JDM version. Also availability of new parts is easy for PKDM version.
JDM version will be slightly more comfortable.
Main decider would be your budget as a clean second hand JDM would cost much more than a similar condition PKDM.
Reliability of PKDM is on par with corolla if it is maintained well but can't say same for JDM.
Due to smaller engine size in JDM it struggles with the body weight of the car whereas in the PKDM the engjne power is optimal as compared to weight of car.
The engine life of PKDM would be more than the JDM since quality of the engine is very good and due to higher torque it does not need to work as hard. I've a pkdm at over 180k and engine is still in optimal condition also ac still blows cold in the June July season.
For long, both are not suitable although the PKDM can maintain higher speed much more easily but cross winds will make it difficult to drive. A sedan is best suited for long but amongst the two I think PKDM would be a better choice considering long distance travel.
