Original mirror for wagon r is 17,500. That is almost the same as Japanese wagon r. Jdm has more features too. I suggest looking into jdm and comparing both.
I did drive pkdm wagon r quite a few kms and i can say:
Made of cheap plastic interior
Build quality issue ( bonnet zor say band krna prta hai, literally utha kr marna prta hai"
2016 model had some rust in engine bay.
Brakes are quite sh!t, almost the same as Mehran.
It has ALOT of blind apots. You cant see the back while driving because the car is very raised, and it has huge pillars on the left and right that made the car dirfficult to drive on corners. Its also very unstable on corners because it is very raised.
Thats why im saying, consider and look into jdm wagon r.
