About the trunk insulation, i visited Bilal Gunj some time ago to buy the Trunk for my 8th Gen. That one did have insulation but the shopkeeper was charging extra 3000 for it. There were a few Thailand imported half cut 9th Gens as well so possibility is there.
But considering you are about to sell your 9th, i dont think you should consider
Well probably not. Because these were most likely from a UK hybrid. I am not sure if Thai or japanese have these tinted ones like this and 9th Gen sedan hybrid wasnt availaible in UK
