Hey i had my last car retrimmed and didn't cost all that much.. If your keen i would hit Daily's in Pilbra st welshpool they are the suppliers of all the materials and that the trimmers in perth use..

You Should be able to do the doors yourself there pretty easy... As For the seats trimcare should be able to change the middle section for you to match the door trim colour you choose...

Theres a place in Burswood that does the moulded floor carpets maybe they could do you a new floor piece to go in...

Good luck thats all i can think of you should be right..
