The milage depends , as I myself am a importer that sums it up, u'll defend imports because ur income is related, the milage is around 20-50k ! and meters are reversed, in japan cars spend long time idling in traffic so milage isn't really a figure of revs covered by engine, maintenance is worse than ours because they consider these cars disposable. 20k mileage can be covered with 3-4 synthetic oil changes stamped at 5000-7000km and we won't know how much the car has idled, ran on high rpm.
The model depends , in range of a Wagon R you can get a 2013 Wagon R(JDM)!
For how much long can you drive Wagon R at 160km/h ? as long as there is empty road available
Is the car meant for racing ? nope but higher top speed means car won't be screaming at motorway speeds of 100-120
Is the speed limit 160 or above ? speed limit is around 100 and these kei's are screaming at 4500 rpm or above at that.
Do these mechanics hold a degree in their field? import some degree holding mechanics too, atleast 3s staff is trained for that particular car.
They say Mehran is durable , do you agree with that! ? mehran isn't durable, atleast it isn't disposable.
And as far as HP is concerned , The CVT coupled with 660cc has enough torque to carry its own weight along with passengers! at rpm thats uncomfortable for passengers due to its noise and harsh enough on engine. btw 3 healthy Pakistani's are easily over the max weight limit, means more drag created on suspension, engine and other components
The new Wagon R JDM also has a motor to assist the engine and electronic air-conditioning along with a start stop!
Claimed fuel economy of more then 28km/l which are not present in PKDM! and the false fuel economy bubble bursts once the cat con is chocked, a highway journey at 100kph(rpm are pretty high), the electricals malfunction.
I hope you got my point and I think it is enough to prove that PKDM is better then used and abused jdms and there is no use of kei's as these cars are not meant to last long enough!
