Well yes Jdm parts r comparatively more expensive as compared to PKDMS but their high prices r totally justified.
Because The Quality of local and imported parts have a hell difference which is why they r more expensive. e.g A Swifts Side Mirror Costs around 3.5-4k per piece whearas Vitz Side mirror costs 7k per piece. Because Vitz Mirror is retractable aswell as has an indicator light.
A Door of Mira costs 15k while the door of a Cultus Swift etc would cost 6-7k. Then again compare both the doors quality and material used. Their is a big difference in the finishing, paint quality ( in case pre painted in required color ) . Interior door sheet ( If included ) the high price seems justifiable.
Another thing which people complain is that plastic prices r insanely expensive. Yes i agree. 3.5k for a wiper tray piece sounds ridiculous doesn't it? But FYI their is duty imposed on these parts aswell and then again compare the plastic tray of a Swift or Corolla and that of a jdm Alto, Mira, Vitz etc. Their is a big difference. The high price is actually worth every penny.
