You're kidding right? Bilal Gunj FTW!
A little advice here: if you wanna get door trims: grey ones are expensive coz they match your factroy interior, you see. Get black door trims AND black dashboard. That should cost you roughly the same a grey trims alone. Get a matching steering wheel and black seat covers and a couple of kick panels.
That way, not only you'd avoid fifty shades of grey inside your car, and it should look more exclusive and beautiful in black.
You can keep original stuff with you and just pop it back when you want to sale the car.
