vinyl seats are made of that material due to the kits basis from the DDA diecast models which have opening doors and the company owner advised me that the "soft" seats were to allow the diecast collectors to feel the soft seats...........lol......yeh right......but thats what I was told..........otherwise the DDA kits althought they do have some drawbacks overall build well AND are models of Australian cars that have never been available........thank you DDA and to Scale Model Enthusiast for the review............andyd
