suzuki every wagon is 660 cc JDM product.
as per this forum and the ground check there are no new spare parts available for suspension or engine overhauling of these JDM 660 cc vehicles.
not sure of your budget but in under 1 million you can search for a local made in Pakistan car. markets have ample supply of new parts for engine suspension and body for local cars. sir ji it is your money invest it correctly.
