Assalam o Alicom,
My Suggestion would be if you haven't bought Vitz yet, then go for F Safety Edition 2, that comes with Carbon Fiber Panel , Chrome Fittings and Handle , Upgraded Seats Fabric.
if you'd like to buy separate pieces, then look for Parts shop that have half cut vehicle or possible stolen interior panel from car. which would be difficult case to source. As they would be mostly be used and have scratches less chance they have shiny and new one.
