I know the shop he uses and they do/have quality stuff. I'll likely do the same as I did with my Speedster build and pick out custom interior colors.
I have been leaning towards a blue leather and tartan interior.
I have named the car "Whitewalker" after the GoT series on HBO... so the colors will be white/blue/black/grey...
I have several months before I even think about the body and interior since I am doin another pan up build like the Speedster.
